Code 26 no start 1987 GLHS
Car is a 1987 GLHS with a MP stage II computer.
I was getting codes 26/27 but after repairing the injector harness which was brittle from heat I drove the car maybe 20 miles and it ran good. Started the car the other day and made it about a mile before it just shut off. Fuel pump not coming on and code 26.
I took the injector harness back off the car and everything seems to be fine. Cleaned the connector, cleaned the other connectors that run above the transmission to the power module. Verified the LM connections and PM connections are clean.
If I turn the key on I hear the asd relay for 1 second then it shuts off, car just cranks. I grounded the blue/yellow wire at the diagnostic port and the asd relay makes a weird static noise, the car also does some other weird things like the fan relay will click and the fan will rotate slightly, also some clicking coming from one of the solenoids on the passenger side. Fuel pump will not turn on with asd grounded. The Power module was recently replaced because of a bad voltage regulator, I'm wondering if the new one is also faulty now? It's a reman from rockauto. The fuel pump has maybe 2500 miles on it, it's a walbro 190 from FWDperformance.
Not really sure where to go from here. Any help is appreciated greatly.
