'89 Geo Metro G10 motor, 5 speed, complete rebuild less than 20k miles ago.

recent background...
had a bad/old fuel pump 3 weeks ago. replaced that. ran great until yesterday. Got in it, tried to start it... nada. just kept turning over. did my diagnostics... bad fuel pump again. I had replaced with Artex? brand or something like that. a mechanic buddy of mine told me they are super awesome and last forever?... no so much. This morning, I replaced the pump with a new one (again). Started right up, runnin smooth again. Drove it around town and on the freeway without any issue....until...I was exiting the freeway and trying to make the light and came into the corner pretty quickly and down shifted to 3rd and dumped the clutch and put my foot in the gas... nada. ?!! I coasted for about 10 yards and feathered the gas with my foot in the clutch (the car didnt die). she comes back to life. I let out on the clutch again and now there is this hard lurching! "vroom....stall....vroom...stall...ect."! So, I put the clutch back in and super tenderly let it back out with barely any throttle...runs fine. Over the next handful of intersections, I learn that i have to super baby the throttle OR 3500 rpm or higher and it runs fine.?

It idles great. Rev great. runs great at steady rpm. I cant tell if the fuel is cutting out or the ignition. The gas tank is full by the way so the theory of sloshing gas in the tank doesnt work either...

I did a few "searches" and am going to test a few ideas this afternoon. I will inform as I get results. Your ideas are greatly appreciated.

thanks

Fixed! ... i think.

The plastic wire connector for the fuel pump was cracked and loose under the rear seat. Replaced with new connectors... all good. No more cutting out.

You may want to check your fuel filter as well as fuel pressure.

Replaced that about 6 months ago when I did the rebuild.

So, all the same symptoms that I mentioned in the 1st post of this thread started again. I know the connection I repaired it solid and is not the problem. It only does the stall thing from a complete stop, everytime. Once I am all the way in gear and going around 20 mph, all is well and it revs, pulls, shifts and idles fine. code 51 came up again too.

ideas?

51 is the code for the egr on cars from 86 to 95. look to see if you have an egr valve. it probably needs serviced.

the symptoms you describe sure sound like a bad fuel pump or clogged filter. the lurching and stalling on acceleration with a good steady state operation is indicative of fuel starvation.

you may also have a tps going bad or way out of adjustment. i'd check that, too.

test the TP sensor.


crap in the tank clogging the pickup?


when i worked for a parts store airtex was by far the worst pump we sold. got those in for warranty returns 3:1 over the other brands we sold.

now....actually working in a shop...theyre all pretty much equally shitty. out of all the pumps we install OEM are the best available.

I just put the new screen filter on the pump and the in-line fuel filter is only a few months old. If it was the new fuel pump, wouldnt the stalling (fuel starvation) symptom occur more often than just when I am starting to move from a full stop?

I do have an EGR. I serviced and cleaned it all out back when I did the rebuild last summer. would it need it again this soon?

if that airtex fuel pump turns out to be the culprit (and i lean towards that to be your problem) use this pump. it's the replacement for the swift gt twincam engine.

http://www.ebay.com/itm/NEW-ELECTRIC-FU ... es&vxp=mtr

i mounted that in my red resto-rod vert in preparation for an engine swap when i repaired the fuel lines and it operates just fine on the old normally aspirated g10 i'm running now. it's physically bigger but it will fit into the metro's fuel door assembly with a little fiddling. you'll also have to do some simple wiring mods to add ring terminals to replace the push on spade connectors on the stock pump.

you may also try blowing back through the supply, return, and vent lines from the engine bay to the fuel tank to make sure they aren't clogged up. also check the steel lines for kinks. don't go much over about 20 psi on air pressure to clear the lines so you don't blow any lines apart. :wink:

Did a fuel pressure check. Holds @ 15 psi and runs up to 25-28psi when i rev it. Normal?
I bought a new fuel filter too. Going to swap that out before another pump attempt.

Also, seems to do this wanting to stall thing after the car is warmed up. Runs great when the motor is cold.

here's the link to the fuel pressure testing thread.

viewtopic.php?t=24569&start=0&postdays=0&postorder=asc&highlight=

unfortunately, the pics were all lost in a server swap. this used to be the go to thread for testing fuel pressure. you may be able to see the pics by visiting the original poster's photo gallery.

15psi @ idle seems low.

Try cleaning your MAF as well.

ok, yesterday I removed the "newest" fuel pump to make sure that the screen filter was still attached ok and that there wasnt something obviously wrong with my prior installation. All was well there. I did some more searching and found that my psi numbers were definitely in the "normal" range. I then took apart and checked/cleaned the fuel pressure regulator. nothing odd there either. double checked all the vacuum lines to be sure they were routed correctly. all good there too. I put it all back together and drove it about 30 miles without the big stalls happening. but, again, it mainly happens after it has been driven for about 45 min-1 hour or so.

I didnt swap out the fuel filter or replace the fuel pump "again" yet. waiting for the problem to repeat. Driving for 9 hours straight on Tuesday, so that will be a good test.

I will post updated info.

your advice is greatly appreciated and welcomed.

thanks everyone

I have now driven another 1000 miles since my last post in this thread. Check engine light has stayed on the entire time. The wanting to die when leaving from a stop has been consistant. Still only does it when the motor warms up. I havent replaced the fuel filter or fuel pump again yet.

Yesterday, i was tinkering around the motor and found a couple of old warn and cracked vacuum lines. I replaced them and went for a drive. I did not reset my ecu/check engine light. Drove to the gas station and filled her up. Still getting 44mpg. When i started the car at the gas station, the check engine light was off for the first time in a long time. Drove around another 15 miles and parked it for the night. Got up this morning to set off on another 8 hours of driving and the damn light came back on and the stalling symptom came back with it. Seams like less power as well?

When i get home tomorrow i will be replacing ALL the vacuum lines and replacing the in-line fuel filter again among a few other small projects.

New theories are welcome. Will update soon.

I doubt a vacuum leak will cause your engine to throw a code. And given that its intermittent, its probably related to a wiring short to a sensor somewhere on the harness. Or as someone said, your egr valve probably needs servicing.

Code 51 is egr related. Bad lines/ low vacuum can throw that code.

Tomorrow i will be diving head first into my bucket of frustration ....

Well... update...

Replaced ALL vacuum lines. Found 2 that were really bad. Also discovered my coil to distributor wire wasnt seated very well? Finished installing all the parts for my ac that i am adding.

Runs way better now. No check engine light. (Went off on it's own) still does the random stalling thing from a stop. Tomorrow i will be swapping in a new in line fuel filter and vacuuming/charging the ac system.

If that doesnt fix 'wanting to stall' problem, i will fork out the cash for 3rd time and get the expensive Bosch fuel pump. After that,... i dunno.

if it is stalling only when it is warm you might want to try swapping in a known good coil.

Hella hot day today. Doing the worst it ever has with the stalling. Now, i can get it to idle, rev the motor with no issues. The moment i begin to let out the clutch, it dies. Cant move. Something is over heating under load. I can only think of the fuel pump or the ignition coil? Going to find out

Odd added note. No stalling when driving in reverse!

It is iver 110 degrees today btw. Diggin around the interwebs and found the idea/posibility of vapor lock? Ideas? Saw several posts about clipping wooden clothes pins to the fuel line to make a heat sink of sorts with huge success? $1.05 at walmart for 50 of em..gunna try it. Ya never know

after more research I have found that the heat can cause a variety of different issue including vapor lock, overheat silinoids, overheated relays a numerous other small quirky ailments. I dont find it coensidental that the hottest day of the year thus far and excessive inner city driving with my new ac kickin added up to this stalling issue to get really bad. I have parked the car for several hours now and just took it for a nice spin. everything works wonderfully again. I did adjust my tps slightly. But, have done nothing else. I will update as I get new info.
