Re: 2 Engine Codes - What to do next
Silly question. Have you cleared the codes after the repairs. I know it is stupid to ask, but some people forget.
On the code 95 have you replaced the Fuel pump? That error indicates that you possibly have a bad fuel pump, fuel pump ground or an open between the fuel pump and pin 8 at PCM Fuel Pump Monitor signal.
Something that you may want to look at also is the multi-function module under the hood. It is ablack box with a ton of wires in it and controls the fuel pump, power, cooling fan, and compressor relays, in addition to other controls. I have heard that in some cases the wire from the multi-function to the fuel pump getting punctured by a body bolt. This is a pain in the arse to fix. You will have to pull your carpet, seats and everything to access the loom it runs in just to check.
Just so you know also there was a TSB covering this as well. RSB89170 NOV 89 Fuel Pump/Sender - Defective Parts Return
This affected the 1990 vehicles as well.
Just a little bit of info for you. Hope that it is of some help.
