Dodge/Plymouth Neon: fuel or starting problem
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

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.
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

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?
1 it has some difficulty starting. it cranks (rather noisily) for 1-3 secs before starting up and then it runs fine. there doesnt seem to be any circumstances that contibute to this like a cold engine or anything like that. at first i thought it was because of the fuel injection because i would pump the gas a little and it seemed to help but then i realised after starting it without pumping the gas that it made no difference. plus i added fuel system cleaner and it didnt help. my mechanic said it might need the throttle body cleaned but im afraid to do it myself cause theres a sticker that says not to mess with it and it costs $60 for him to do it and and dont wanna pay that unless i know it will fix it. i have a sneaking suspicion it might be idling too low too, but its hard to tell cause this car is totally standard and has to tachometer!
2 if im not gentle with the gas pedal when accelerating (especially from 0mph) the whole front end jumps up and down very angrily until i take my foot off the gas. the dude i bought it from said it was the transmission mount but ive looked at all the mounts i think, and cannot see a faulty transmission mount- i dunno exactly what to look for tho.
3there seems to be a slight lack of power. it accelerates pretty slowly especially in higher speeds and seems to crawl like an old rickety bus up hills. it even sounds kinda like a bus. on flatter streets in between 25 & 50mph i can floor it and it goes VROOOOM and takes off. i dont think its the spark plugs because they guy said he checked them hours before i bought it and they were fine. i dunno maybe it just kinda a weak car but most of the reviews ive read said it was pretty powerful for what it is. is this just the way to car is or could there be something off?
also, a general question: theres a bit of rust in the cooling system and once i noticed a very small leak from the waterpump but i havent seen anymore leaking and the temperature gauge never goes above 1/2 way up, even on hot days when ive been driving around town all day with the ac on. should i be worried?
I know that this looks like alotta crap about nothing but if anyone sees a connection with anything or has any ideas or has had similar experiences, i would just love to hear about it!!!
2 CHANGE THE MOTOR MOUNTS ANYWAY, AT 140K THEY ARE PROBABLY SHOT, THEY ARE SOFT TO BEGIN WITH AND WITH AGE GET HARD. AFTER MARKET ARE THE WAY TO GO BUT START OFF HARD AND THEN THE ENGINE VIBE GOES AWAY, YOUR CHIOCE.
3 CHECK YOUR CATALYST CONVERTER ON THE EXHAUST, USUALLY IF A CAR RUNS FINE ON FLAT GROUND AND THEN LOOSES POWER PULLING OR UP HILL IT IS THAT, FROM PERSONAL EXPERIENCE, AND DO TO THE AGE OR MILAGE ON IT.
4 CHECK OUT WWW.MODERNPERFORMANCE.COM YOU CAN FIND RESONABLY PRICED PARTS WELL UPGRADES AND WILL BE SURPRISED ON THE OUTCOME. HOPE THIS HELPS YOU. :sick:
Any thoughts other than a new fuel pump?
