Hey guys i have one that has stumped me and i want to see if other people have any ideas.
First off this is an intermittent problem which only happens occasionally, which is very frustrating. The car wont start it has spark compression but no fuel. I found this out by spraying starter fluid into the throttle body and it started right up.
Heres the things i have confirmed to be working
1. Fuel injectors, they all have good resistance and are receiving 12v at both connectors
2. MPI relay tested it via This linkl and all three tests were per spec
3. ECU is fine, doesnt smell check engine light goes off when key is in "ON" position and boost gauge goes to 0.
4. Has a little under 1/4th tank of gas
5. Fuel is getting to the fuel rail it spilled out when i disconnected it.
6. Injector resistor pack tested good via This link
7. Fully charged battery jumped to another running car.
It seems like my problem is from getting the signal to "fire" the fuel injector? I dont think both wires should be showing 12volts but i dont know. Thank you for your help with this. One last thing, the car started perfectly and ran for 3 min yesterday and now today it isnt starting =(
