I rented the code reader at Autozone and did the fuel pressure test too. I had to remove the air plenum to reach the schrader. Well hidden. Pressure jumped to 40# and was rock solid for 10 min. Bled down to 10# and it stayed there for 10 min. I was able to keep fitting on and got plenum on. Pressure with engine on was 48# including shutdown of engine after running 11 min. with water temp. about 1/2 scale.
When I drove up to Autozone this morning about 2miles keeping my foot on throttle about 1000 rpm, engine did'nt shut down. When I went to leave, engine would'nt start until I gave it a dose of starting fluid. I drove home tickling the throttle. As soon as I let off throttle, it died.
Read codes at this time: 1of6 P1700 manufacturer control transmission
2of6 U2108 manufacturer specific DTC(see service manual)
3of6 P0500 vehicle spd sensor A malfunction
4of6 U2108 (same as 2of6)
5of6 P0727 engine spd sensor circuit no signal-pending
6of6 P0335 crankshaft position sensor A circuit malfunction
Erased codes. U2108 remained. Had to erase separately. Turned ign. switch to on and code U2108 came back on.
Just tested again. Needed starting fluid to start 1st time.Engine ran great. Went to fast idle 'til warmed up (about 1000rpm) then settled at 500rpm. Ran 12 min. and shut down.
Read codes: 1of3 U2108
2of3 P0727 engine spd sensor circuit no signal- pending
3of3 P0335 crankshaft position sensor circuit malfunction-pending
Where do we go from here? Anymore tests? A new crankshaft position sensor is $56.49 at NAPA. Should I try that? Before the last test, I changed the plugs and rechecked all vacuum lines and electrical connectors.
