86 running real bad !!
Bought the 86 ISP in Feb 2004. Since that time it has had about 200 miles put on it and the fuel pump gave out a couple years ago and it has sat. This week I dropped the tank and put in a new fuel pump, new fuel filter, fresh fuel with seafoam. Car runs like total CRAP ! I put on an NOS IAC valve, cleaned the rotor button and distributor crap real well and it still runs like CRAP ! Hard hard hard to start then have to constantly pump the accelerator to keep it running. Pulled a couple of plugs and they are pretty nasty. Tomorrow I am replacing the plugs, rotor button and cap and if it still runs like CRAP ! I am going to replace all the injectors. Not sure what else I can do...... I also put in a brand new battery because the one it had in it died about 5 years ago.

ouch i feel your pain! did you check to see any rust in gas tank? that's what happened to me with my 89 SSP after not running for 7-8 years, rust was all over so i dumped the tank and got a new one, never had a problem ever since.

Replace the fuel pump relay under the passenger seat. I had the same symptoms on my 86 GT convert 15 years ago (24k miles) when driving the car on my honeymoon (had to leave the car at Ford dealer half way to our destination and get it on the way home).

Check the IAC (idle air control) valve. This and the 10 pin connectors on the back of the EGR plate are common problems for idle issues.

really? can you post up a pic of that connector? mine almost have perfect idle but just a tad off and annoying because voltage gauge kept rocking at idle but driving is fine. no vacuum leaks or anything.
