Are your plugs getting fouled?
Spray some starting fluid into the intake and see if it tries to start. If not, do a compression test on all cylinders.

87 percent on the TPS? That's clear flood mode which cuts off the injectors. There may be a fault code set too for TPS signal voltage too high. Check the voltages on the three TPS wires. One will be 5.0 volts, one should be 0.2 volts, and the signal wire should read between 0.5 and 4.5 volts, (close to 0.5 volts at idle). If all of them are near 5 volts, there is a break in the ground wire. If only the 5.0 volt feed and signal wires are at 5.0 volts, there is a break in the signal wire inside the connector or sensor. If only the signal wire is wrong, (close to 5 volts), but it changes when you move the throttle, it was turned before it was tightened and is installed incorrectly. That's pretty hard to do.

Gotta get that TPS percentage down closer to ten percent.

ok i bought a meter stuck the com/black wire in the ground on the plug then i put the red wire on the first orange wire on the plug and got a 5 1/2 v then i stuck the red wire in the middle orange wire on the plug and got the same 5 1/2 v. i put the back wire on the neg of battery and the red wire on the ground on the plug and got nothing (no volts) what does that mean.

im starting to think too the PCM changed the plugs today anyway

I'm a little confused so here's a better test. Put the meter's black lead on the engine block or the battery negative post, and the red lead on the center terminal in the TPS plug. Take three readings, one at idle, one at half throttle, and one at full throttle.

You should find close to 0.5 volts at idle and close to 4.5 volts at wide open throttle. The voltage should go up and down smoothly as you move the throttle. If it does, both other wires have to be good.

Since you have a scanner, you should see the same change in voltage when you view live sensor data. If you do, there is something we aren't interpretting correctly about that 87 percent.

Caradiodoc: I did that test and there was no change on the meter. it started at 0.5 but it did not change i moved the throttle by hand under the hood. when i put the red lead on the other orange wire on the plug it pegs the needle on the meter.

( I appreciate your help)

when she went for a sticker a year ago the guy said that the number 2 cylinder dont fire the plug was soaked. but it ran fine before it just stopped.

Okay, I just finished copying diagrams from the Chrysler web site one page at a time! The wire you're after is the orange / dark blue. You should find very low voltage at idle and close to 4.5 volts at wide-open-throttle. If you do not, check how it is mounted and check for 0.2 volts on the black / light blue and 5.0 volts on the orange wire. If all of those voltages are correct, there is no problem with the sensor itself. You should see the same voltage change on the scanner. If the scanner shows 5.0 volts all the time or close to it, there has to be a break in the orange / dark blue wire.

I did the test the orange/blue works smooth but the orange spikes the meter. I did replace the (PCM)with no luck. can I cut the orange wire at the (pcm) plug and the (tps) run a new wire?

Caradiodoc,
OK are you ready? Day one on this jeep i noticed a shiny spot were the cam position sensor mounts my neighbor who is a Tech said that nothing,well today i loosend the bolt and turned it back and the jeep started right up. The 87% fuel comes from the cruse control sending too much juice back to the (PCM)so there is a wire short some were. I spent $453.00 on stuff, when it was something I found that would have been free. but if this comes up again you might have an anser for someone else.

Thank you for all your help you did a lot of work for me for a $10.00 donation. your a good man/woman REALLY THANK YOU.

Hold the phone. Thank you for the kind words, but tell me again exactly what you found. What had the shiny spot? Which bolt did you loosen, and how did the cruise control play into this? Gotta add this to my memory banks.

Caradiodoc,
the shiny spot was on the block were the forks bolt down for the cam position senser, I saw this shiny spot the first day but my neighbor who is a tech thought this might have no play in the problem. so I just loosend the bolt and turned the CPM till there was no shiny spot then tightenthe bolt and it started right up.

when started the The TPS reading went down to (0%) on the scanner but when shut of it would go back to (87%) thats why i think that there is a broken wire some were on the cruse control.

Sorry it took so long to get back to you but once this was fixed it was on to my Bike Twin Cam HD Ultra classic, cam swap what a job it was the firs Twin Cam Cam swap for me, and Lacona is comming.

Again Thanks for your help.

Good job. Happy to hear you're all set to buzz off into the sunset.
