Rockauto.com has pumps for under $70. I just got one for my 4.0

Friend gave me a computer out of an 89 cherokee. hooked it up to my truck now it runs great!

not to hijack but do you need any electrical stuff for the 241 or is it completly mechanical? any vaccume lines needed? I'm putting a chevy350-turbo350 in my truck eventually.

Vehicle referance. AKA supply wires 5 volts. I'm going to check the ground today.

ok well I hooked the scanner up again and I had 2 ex-master ford tech dudes look at it. They were saying how crazy all the readings were and there was 5V at the O2 sensor. They think that one of the VREF wires for one of the sensors has shorted out and is messing the whole system up. OR the computer is bad. MY idea is to OHM all the out put VREF pins on the computer connector to ground. if there is very low resistance then I found my problem??

I replaced the IAC. And it runs the same if I unplug it. I replaced the MAP today. No difference. Took the plugs out and the centers were whiteish gray and they were black around the outside. The truck runs rich. You can smell it, it gets 10mpg, scanner says the O2 sensor was lean. Took the cap off. There was white buid-up on the points and the rotor end was a bit dirty. I cleaned it off with sandpaper. NOTHING I just did the fuel filter not too long ago. All my friends have bad compression cherokee's They all blow air out of the oil cap, there oil has gas in it and they are slow. MY truck's oil smells like oil and there isnt any air coming from the oil cap. Ill look up on the trans sensor and stator. Thats my next project :thumbsup:

IAC works I adjusted TP to exactly 0.8v MAP supply volts is normmal 5v. Running it jumped between 1.5 and 2.8 allitle high but I'm guessing this is because the crazy idle. I ohmed the ground wire and it it had 3ohms of resistance.... NOT GOOD? I'm going to try a better meater later today. The truck isnt stalling as much it just idles like crap and not %100 power.

I had the scanner hooked up to it to. The timing is 10* advaced. Then when the engine revs up by its self it jumps to 35* advace :hateputers:

cleaned the c101 conector and the on to the right of the booster. Now it runs really bad. idles rough then rps will go crazy high every now and then. tps idle volts are around 7.3v Should be higher I know. When the truck idles rough the fuel pressure is at around 38-40 then the pressue will drop to around 30 and the rpms will spike then run good for a few sec until the fuel pressure goes back up. MAP vacc line is good. I hooked the smoke machine up and no major leaks. HELP :???:

cleaned out the connectors. now the truck runs worse.. I'm going to glob some greese on it later and see if that fixes it.

Ive cleaned the TB and IAC and replced it and cleaned the hole that it goes into 5 times already. I adjused the kick-down all the way tight and all the way loose. Not much difference. My next step is to clean out that connector then

The timing chain has never been replaced that I know of. 130k but id like to try other stuff first before riping into it. How should the kick down be adjusted? I have it so when your at idle it has a little slack. I kow ford the way you do it is to put a pressure guage on the TV port on the trans. Same with jeep?

by the way here's the beast 318128_3556567686293_1635775989_2728341_1562343636_n by mtbtyler666, on Flickr
