Guys I'm stumped. My engine was recently rebuilt in the last couple years and I'm working out gremlins. 1.7 fuel injection runs and drives great but when it gets really hot ( I'm in Dallas area), it starts to run erratic. I have to pump the gas or keep it revved high to make it home. When trying to start it. I have to keep pumping the gas to keep it going. I have...
- fuel pressure about 28-29 lbs.
- Bowlsby FI harness maybe 4 years old.
- rebuilt Bolwsby MPS (I've switched out with others) and get no difference
- swapped CPU's; no difference
- swapped coil; no difference
- new 914 rubber HTS; 2200 ohms cold @68 degrees; 118 when hot
- FI points near zero resistance
- no vacuum leaks
- recent valve adjustments (a couple just to make sure)
- fuel pump relocated to front for over 30 years
- pretty new Pertronix ignition (the previous had failed after 10 years)
Any ideas? Thanks
