74 1.8 Got power to pump/builds good pressure, got spark,double relay seems ok, ---engine starts on starting fluid. injectors sprayed when I jumped to the battery, this is driving me crazy! the resistors show continuity, but not any resistance. could this be the problem? any help would be greatly appreciated especially ecu pin #'s & stuff- - I think I'll go burn my haynes manual now

Resistors checked out good at 7 ohms. Injectors good. what kind of voltage should i get at the injectors? I have an extra computer & injection harness that i swapped out already with no success. the harnesses are slightly different though. i think one has the leads for an altitude compensator. other than that,they're the same......... right?

Might have to scroll down. The link at the bottom no longer works, but the list of components has links to help you test them. The Cap'n |
