Fuel pump problem-no three second prime or purge
#13
cel lamp glows with key on, like it should

question Q106 is tiny transistor? Or looks like black FET style?

I did not see it clearly marked on your image. i will inspect again today (checked yesterday no bad caps no obvious damage no burnt crispy traces, no smell )

Next steps.
will connect scan tool.
check and correct or remove any bad hacks to wiring.
check TPS voltage.
will check grounds and voltages at ECM pins
any other steps or items to test?

**
stereo wiring-previous owner hacked. Plug still there but some wires missing, some cut.
Brake and signal wires hacked. relay under dash added to control signal and brakes from rv tow vehicle resistors added behind tail lights in back
.**

thanks as always your experience and knowledge means a lot. you put a lot of time into your site. its very appreciated by many (me too!)
