OK - this all started a while back with the engine dying after running for a while and getting warm. Extensive troubleshooting followed.
Here is Where I am at: New SMP Injectors and injector seals. Connected HF fuel pressure gauge. Fuel pressure is good. After installing new injectors, it ran good, until I broke one of the fuel injector connector wires while buttoning things back up. Checked out the harness, and it is pretty questionable, even if I made the repair I could see. So, bought a rebuilt harness from Bowlsby. Installed FI harness, and while I was in there, I replaced all vacuum lines, including the manifold connector hoses, and intake manifold gaskets. All back together, now it cranks and gives 3 outcomes: 1: No start at all 2: Fires, runs for a cycle or two, then dies 3: Fires, revs up to about 3k, then dies (throttle action makes no difference) I have rechecked all harness connections, they are solid. Rechecked vacuum lines, they LOOK correct, but we all know that if it looked right the first time, it will still look right the second time. Help!!!! I am in MN and only have a few more weeks before the dreaded white crap falls from the sky and ends the season. |

you been having this problem for a while @SteveL ?
here http://www.914world.com/bbs2/index.php?sho...=355253&hl= http://www.914world.com/bbs2/index.php?sho...355078&st=0 ? it sounds to me like the car is starting off the cold start valve. but the injectors themselves are not opening. runs out of the gas from the cold start valve and then dies. you describe three different types of attempted starts. is this on different days or different ambient temps/time of day? or just three different types of behaviour at the same time of day. it does not sound like the injectors themselves. they are new? but maybe they are not getting a signal. maybe someone can guide you through some methodical steps to get to the bottom of it. to check the electrical side of things. someone will see this thread and assist. |
