Newbie here tryin' desparately to avoid the dealer for repairs on my stock '97 F250 7.3L sclb.
A month ago my truck ran PERFECT, except for the popular "fuel leak in the engine valley" I cleaned the thick layer of crud from the bottom of my fuel bowl. No visible cracks, a few pitted area's but nothing too deep. I degreased the valley and put it back together to drive so I could find the leak. It started running terrible after about 10 minutes. Sat for a few weeks so I bought AE
Scan Tool for Fords.
Last week I replaced the screen and O-rings on my FPR, (screen was coated with grime.) Started it up and ran great. I configured AE
ScanTool and it reported no DTC's. Drove it for about 10 miles and the CEL
came on, started to get sluggish.
Went home and plugged into ScanTool:
Injector Control Pressure Higher/Lower than Desired ( Engine running.)
Then I ran KOEO
Test and got:
P1280 Injector Control Pressure Sensor Circuit Low
Over the weekend I replaced the entire fuel filter canister assy. Drove and same thing happened, same DTC
Last night I unplugged & checked the ICP
wiring & connection. It looked like corrosion was happening inside the connector on one of the pins, so I cleaned it good. Then I unplugged the IPR
, inspected the wiring and connectors. Removed the IPR
solenoid so I could check that part of the connector. Cleaned the connectors and put everything back together.
Now my truck won't even start!
ScanTool shows: P0344 Camshaft Position A Circuit Intermittent
What could I have done to cause the CPS
to die and does this mean I need a new CPS
? When my CPS
went bad a few years ago, the truck would start, but would die at random times. Tonight I'll put a new CPS
in and see if it starts. If so, I can rescan to see if P1211
& P1280 are gone.
Anybody got any ideas?
My co-workers keep telling me to try Obama's "Cash for Clunkers." I'm beginning to think the harder I try, the deeper I get. No smilies in this post because I'm not doing much smiling lately! Sorry for the long post.
