So I have been reading a lot of post about problems with the 80's fuel delivery systems and I can't decide which to replace first. Here's what I have. 89 Cherokee Laredo with automatic and 4.0. Here's what happened. Driving down the hwy and the old girl starts sputtering and slowing down. she would go for a little bit and then wouldn't go over 10mph. Took it to a transmission place and it is in good condition. Took it to the local Jeep Dealer who wouldn't touch it because it was pre-OBDII. She will not go even if gunned and is a bear to just get started.
So I started reading here and found that the TPS and CPS can cause similar issues. Also a month prior to this happening a coolant line busrt and blew SH*t all over the engine bay and other threads I have read said that the IAC can have similar symtoms and are prone to be bad if they get wet and IT GOT WET!
Anyway I started last weekend to check stuff out and when I went to release the Fuel pressure from the valve there was NOTHING. So I started it up and let it get going and let it run for a half an hour. Then I shut it down and let it cool for another half an hour and checked the fuel pressure. STILL NOTHING!
So, on to the question if you could only replace one thing at a time where would you start; the Fuel pump, the CPS, the TPS, or the IAC? I am short on cash right now but can aford to replace one item with one NEW item ( only Choice for me so don't suggest junk yard for this stuff ) once every pay check. Where would you start given that all four and maybe the EGR are bad?
Thanx:tears:
