KOEO codes
14 engine rpm signal fault or PIP circuit failure
29 insufficient input from vehicle speed sensor
41 oxygen sensor circuit indicates system always lean
66 mass air flow sensor circuit below minimum voltage
95 fuel pump secondary circuit failure
when truck was running it had no OD and no lockup, I replaced the VSS on the speedo cable but still get code 29.
the last time I tried to drive it, it kept stalling. Had low fuel pressure. I figured it was a bad pump so the truck was parked, (this was late April and snow was gone so I got the summer car out of storage 1972 Maverick)
It's now time to fix the truck. I installed a new sender and pump. I went with the complete unit a the fuel gage did not work, (still don't).
The truck started but ran like crap. figured it had air in the line, so I took it for a drive. The engine ran but would cut out (not a stumble like running out of gas but like turning the key off and on) I got it home.
Next day went to start it but had no spark.
so I replaced the crankshaft position sensor, Now it has spark but still won't start. Once in a wile it will try to start but will stall when I let go of the key.
