I've tried searching the Faq, & nothing came up. So here goes my first post. It's an 88 SE converted to 5-speed. Battery went dead a day & that is when the problem started. Checked the EGI fuses & both are good. Pulled the injectors & both read 3ohms, & both click when hooked up to a battery. Main relay checks fine. So does ECU & AFM. Fuel gets all the way up to the injectors just not out, so I know fuel pump is working. Any replies will be appreciated.

 

As long as your injectors are within the Resistance reading,(1.5-3 ohms on 1986-87 )**(Non-Turbo)** (12-16 ohms on 1988 models) **(Non-Turbo)** which was what you did first, you need to check the resistance in your crank angle sensor, that will tell you if they are getting the pulse width modulated signal from the PCM(duty cycle)= (on and off time). To test it you need to disconnect and ohm the connector.. **(See picture)**..test continuity from terminal G1-G2 and Ne1 - Ne2...Values should read 110-210 ohms.. now (phew) if that is still ok, you need to check your solenoid resistor..**(see picture again)**1986-87 models..(5-7 ohms)..check continuity between Terminals (A-B or C-D)those can go bad too once you have tested all that you should find your problem. It's all about testing and elminating the good parts in the system, that should lead you to your problem...oh and I almost forgot, make sure that the ignition switch is clicking that main relay on !

good luck...

Thanks Dave. I'll retrace my steps & follow what you posted.

 

That would be a problem. Only 86-87.5 FC's should have low-imp injectors. An 88 should have high-imp injectors that measure ~13ohm. I'd expect fried injector drivers in the ECU if you tried to use low-imp injectors without resistors.
