This is taken from another forum im on and has gotten no results. Figured I would try it here.
I am working on a car right now that wont start. I have checked everything. I verified timing at teh crank and dizzy,spark,fuel at the rail and injector firing. I ran a scan and only code is cyl 3 misfire. He has had this code for a while on and off. I will do compression test in the morning. My question is, the scan showed the TPS at 9.8 on start up. I am wondering if teh TPS is bad and the mixture is to rich on start-up. I pulled the plugs after cranking and they are dripping with fuel. What should the TPS read and start-up? If the crank position sensor is bad then it would explain it not starting but there is no MIL for it or the TPS. Any info is greatly appreciated.
second post I made after further touble shooting.....
So I did the compression test and I got 150-165 in all 4 cyls. Fuel pressure is at 32-35 lbs. I wonder if he just got really bad gas! The tank is full. The gas smells "funny" on the plugs but is dripping of the plugs after just a couple of cranks. If the TPS or CPS were bad it should show on the scan.........I guess I could swap the ECU with a known good one and see if that helps. Any ideas? If I hold the gas peddle down and crank it, it almost wants to start. Kinda like an old school car that has been flooded.
Maybe someone on here will have an idea of what could be wrong.
