Cranks but No start Question

[TooFoxy]

Just as stated the car will crank but not start; I am familiar w/ the checklist and have went down it. I am to the point have; fuel pressure; have spark but injectors will not fire. i checked for continuity between the black/orange(eec relay) and red (black injector harness connector). there is continuity and no shorts, BUT w/ the KEY ON no continuity and it is Grounded(shorting). Also the fuel pump runs endlessly never had done this before.

Its an 88 GT(maybe useful lol)

I had a similiar promblem....but my fuel pump didnt run constantly. It was a bad TFI(control module sensor) located on the distributor.

Check for 12 volts on the injector red wire. No 12 volts, check the EEC relay
located on top of the computer. Also look for 12 volts on the black/orange wire on
the EEC relay - it is the power feed to the computer.


Check the red/lt green wire on the EEC relay - it is the power to the relay coil.
Check resistance on the black/lt green wire and ground. it should be less than 1.5
ohms. The black/lt green wire is the ground for the EEC relay, a must have ground.
