Have you performed a fuel pressure test? Should be around 32 psi when idling.

Is there fuel in the tank?

Has the fuel filter been changed out to a new one?

Spark plug wires seated and securely fastened on the spark plugs and the distributor?

Is there gas in the tank?
Do you hear the fuel pump run when you turn the key on?

***Let me say at this point, that if you don't use the following information for your '87, then at least print it out for future use. It is nearly impossible to find when you need it.***


You can check trouble codes. The ECU is under the passenger seat. You'll need a 12mm socket, an extension, and a ratchet to remove the seat.


Here is the sticky from the Hardbody section. Look at the bottom of the first post, and you will find this tidbit:

Expose the ECU, set the brake, shift into neutral' and turn the key to "ON" without starting it. You should see the LEDs flashing in sequence. If not, flip the switch the other way.

Now, fully press and release the gas pedal one time.
Press the clutch and shift into first. Release the clutch.
Press the clutch and shift back into neutral. Release the clutch.

The only code you should see is 44. Four long blinks followed by four short blinks.

...
[This technique] clears two codes that will otherwise persist. 24 Neutral switch, and (if memory serves) 42 TPS.


Here is a link to the codes.

Hopefully that will get you fixed up. The ECU with the switch was only used in '86 and '87 that I am aware of. (In the USA)

Three things to check.
1)neutral safety switch
2)stater relay near battery
3)ignition switch on steering column.

We are about to pull passenger seat out but we have replaced ignition switch and relays and can hear fuel pump and gas tanks full. Gonna check neutral safety switch. Bout the last thing it could be. We have power everywhere.

You don't mention... if a manual trans, check the lockout switch at the clutch pedal.

Should be up under the dash. Find the pedal and follow it to the switch. Pushes the switch when the pedal is fully depressed.

To replace you remove the bad one and plug the good one into that spot.





I wouldn't try to "fix" as whatever you do to fix it will not have the same fuse properties as it should.
