I am trying to fix a friends care he took it to the shop cause he drives for about 12 miles and it will die. most the time you have to let it sit awhile he says to get it to start, the shop he took it to said he had a cracked fuel line. i checked it out even though i new it not to be true no problems. when it dies the coil pack still works so that aint problem check release for fuel on the rack and find it still has fuel seen a post on tps i am wondering if it would be worth it to replace or not thanks

Fuel pump cutoff by ebraml

i have a 97 neon with 195k miles (haven't replaced the gauges and speedometer often isn't working)... everytime I need to fill up the gas pump cuts off every .2 gallons pumped. i have to hold the handle at the slightest pressure to get just a little gas to pump before the pump cuts off. This is getting really annoying and has beenhappeneing consistently for 6 months or so. Is there a trick to getting past this? or this is indiciative of a another problem. everything seems fine, mileage is good, everything seems to be running well (knock on wood) please help and thanks in advance

96 Plymouth Neon with steel fuel tank - fuel filter? by rooineck

Folks,
 
The steel gas tank has a different fuel filter/regulator setup to what is described in the Haynes manual for the more common plastic gas tank.
Has anyone any experience with regard to replacement of the fuel filter in the steel tank, or where I can find related info?
What part are we looking for?
 
The car stalls after about 15 minutes of driving.
The engine cuts out totally, even when doing 70mph on the freeway.
Leave it a few minutes and the car goes again like a dream.
Engine purrs smoothly and plenty of power on pull off.
 
Having perused the forum I have an idea to replace the EGR valve, but I would also like to check out the fuel filter.
 
The local (no longer) trusted mechanics have replaced the coil twice, plug wires twice, plugs and cam sensor without resolving the issue.
Timing belt and water pump are new.
Fuel injectors flushed about a year ago when the problem first started.
 
Now I take matters into my own hands.
 
This is a 96 2L SOHC manual shift Plymouth Neon with 63000 miles and in otherwise excellent condition.
  
Any assistance will be greatly appreciated.

Lower end Power problem by aknarf

Ok folks put on your thinking caps. because I got a good one for anyone that can help me out here. I have a 2000 neon Automatic have done a few mods to it .. nothing special .. CIA / HIGH FLOW CAT / MOTOR MOUNTS / GUTTED interior/ complete lowing kit. here is to prob.
 
From about 0 to 30 miles per hour the car falls flat on its face.
from 30 to over 110 the car motor has more power then needed
 
Transmission has been custom built with Manual Valve body and approx 2700 stall converter with No internal clutch
 
Trans does not communicate with PCM as been disconnected
 
Prob is not in the trans you can hear the motor completely bog down until you get about 30 - 40 feet down the road then it stands right up and takes off...
 
not an shifting issue does this in first gear. every time not just sometimes. EVERY TIME.
 
was told adding a aftermarket fuel pressure reg would help but there is not return line so this is a prob
 
any thoughts on this matter would be GREATLY appreciated

Does this part Exist? by cowboyup8

I was told that the possible reason that my Neon might not be starting is that the clutch saftey switch might have gone bad. It is a 1997 1.5L DOHC FI Man Trans. Does this part even exist? If so where is it and how do I replace it and or test it before I do.

I never did find out what was going on witht he 95 i had i ended up getting rid of it. but i just had a nother neon doing the same thing come in to my old work. i ended out finding a broking wire on the back of the altanater. it was bring on the ASD relay because that is where it get the 12volt ref. and thats where the green and red or was that green and ornge wire starts from for the injecters, O2, coil, and alt goes to. let me know it that helps you out.

Reving and changing gears problem by skyytv

Hello,
 
My name is Carlos and I own a 2000 Plymouth Neon which has given me all sorts of problems from day one. But I love my Neon and refuse to let it go. I've had shock absorber issues, tire issues, had to buy a new PCM, CAM bearings replaced, had alternators and startes replaced, etc...
 
After replacing my PCM cos' the old one died out on me, my car isn't the same one I use to drive before. The car takes off perfectly but when stepping on the gas pedal to gain more speed, you hear the engine make a "WHOOOO" sound...like its pulling back (misfire?) and then you'd have to press it down a few times to get it move faster. What could be the problem?
 
My mechanics say it could be a fuel pump? Or should I just change oil and get the fuel lines purged?
