Dies, low-to-no accelleration, ICP sensor/part differences
My 7.3 has a new ICP sensor & now it starts & runs some, but dies as you slow down, cutting out running completely & strands you overnight not starting or accellerating, for some reason later deciding to run some so I wonder if the ICP sensor needs gel at the connector point? The connections are very clean. I want to check the injector glow plug connectors in case someone that worked on it prior didn't make sure there was no oil on them so I'll go try to get a manual showing how to do that tomorrow. Does anyone know the name of a really good manual I can get & where to get it? I'm not a guy or someone with extensive knowledge, but want to start trying to do some things myself if possible that costs less. I am so grateful for this site. I have also wondered if it was injector connectors or a fuel pump or throttle position sensor, some part stores call that a throttle switch control, but I wondered if maybe that's a different part? Can someone tell me what a IPR is? Now this got confusing because NAPA's throttle position sensors didn't have the right connection end & when the part was returned they said they didn't carry the one my F250 has by the accelleration pedal. Same with the local Ford. Does anyone know where I can order the right replacement throttle position sensor to try to see if this is what it is?
And what the difference is between that & the glow plug relay? Also, would a cylanoid not distributing power properly caus it to die? Mine seems ok but I don't know. I have a good Snap-On digital multimeter but need a good mechanic book to show me how to properly test the cylanoid. Any good books & where to get them would help because it's slow going trying to ask people for every little thing. After breaking down 2 days in Thermopis, Wyoming a couple weeks ago, I had to pay $266.66 & why it went down ignoring the accelleration pedal was not resolved. After 2 days in the shop with the mechanic unable to start it, at all, or resolve, it suddenly 'just started.' Codes didn't aid in showing anything related so after resetting codes, broke down again over night in Moses Lake, WA a couple days later the same way. It started the next day but was sputtering, grabbing real bad not accellerating or going forward smoothly at all or properly when it did start the next day. It would smooth 'some' on a higher idle after it would start again, but not at all on the low idle. Does reach a point though when it dies where it won't start. It was just terrible to watch & so discouraging. Almost all my injectors are new but 2. Engine is rebuilt with about 660 miles on it, it is really discouraging & unsafe to have to fear being stranded on the highway far away from everybody. And in the cold weather this is even worse. I appreciate anybody's & everybody's help very much & thank you.
