Hi Folks,
I have a 1988 2.9L ranger, 5speed, 2WD, 76K mi, that doesn't start.
It cranks over almost starts but its like not getting enough gas.
I can get it started by holding the gas peddle to the floor then let up just a little while cranking. This method works on warm/hot days. On cooler days (less than 60F) I also have to remove the connector to the TPS
Once started it runs fine at any Temp.
Things checked:
CODES just 11 (all OK) and 63 Throttle Position because of the above starting method
Spark with timing light clamped to each wire checked while cranking.
Fuel pressure at rail (39psi key On, 32 wile running.)
I removed each injector and cleaned them (pulsed with 9V while cleaning)
Pulled each plug and re-gapped they all looked clean
ACT Air Charge Temp (voltage=2.45, ohms=20K at 90F)
Timing
Air Bypass
Parts replaced:
EEC (computer) used
ECT new engine coolant Temp (changed twice)
MAP new (absolute pressure module)
TFI Ignition Module new (keep a spare)
EGO tried 3 different used O2 sensors
What have I missed?
Thanks for any help
