What is happening is yes the injectors may in fact be clogged or there may be blockage in your fuel rails to. also check your fuel filter on your fuel line because that could be dirty and clogged. also perform a fuel pressure test check . replacing your fuel pump is the last resort.

Check your output pressure from the pump where the fuel filter is and reference that to specs. if thats fine then try running a fuel system cleaner/treatment

I put a new rebuild tranny in a 1995 Dakota 4 by4 and now it won't run for crud! Sometimes you can get it to idle for lil bit. But you can't rev it up it anything. Iv replaced the fuel pump ,throttle...


If the car shows these symptoms when in neutral, then it is likely not an issue with the transmission.
Start with checking the basics. You mention it had been sitting for two years. The first thing I'd do is drain the entire fuel system. Fuel usually won't sit for that long without waxing. This is where the make-up of the fuel itself changes over time and causes it to lose it's flammable nature. It will also tend to clog and damage components within the system, including the fuel pump and injectors. You MUST clean the system and refill with fresh pump fuel before attempting any further diagnosis.

Old '87 ranger been sitting in folks yard few years. fires up fine, but spits and sputters going down the road


Old fuel in tank, fuel filter clogged, plugged/clogged carb. or fuel injectors.

1. Drain fuel from tank and replace with new fuel with SeaFoam or Lucas

2. Repace fuel filter

3. With engine running at a high idle and air cleaner off, spray or pour carb/fuel injection cleaner into carb/fuel injectors.

If problems persist, check plug wires for cracks and/or breaks. Pull spark plugs checking for fouling.

2000 Ford Exp. doesnt want to start after sitting awhile. It does turn over but thats about it could it be that fuel injectors are clogged


A bad fuel pump will also make it hard to start.Since fuel injectors are expensive it would be beneficial to have them balance tested to make sure that they are bad and its not a bad fuel pump or pressure regulator.

When u push on the gas it spits and sputters, it ran out of gas like 2 weeks ago and yes sometimes i do let it run low on gas. It spits and sputters when i turn a corner or go up a hill


Could be a clogged fuel filter, and or dirty fuel injectors. Try running some strong injector cleaner through it. It may take 2 or 3 times before it cleans the injectors out fully.
