You should have battery voltage or close to it at the power wire to the fuel pump. you may want to try a fuel pressure test to check the output of your fuel pump.

    there is a time frame for checking power at the pump. when the key is first turned on power is only going to be there 1 to 2 seconds. you would have to check that with someone else turning the key. or have someone crank the engine while you check the power available. I dont know if youve done that, but i dont want to send you all over the place.

My 1998 dodge neon wont start until i pour gas in the throttle body then dies out when i press the gas


What is the fuel pressure when the engine is running ?
Has the filter been replaced ?

Aug 16, 2012 | 1998 Dodge Neon

1 Answer

No gas coming out of the carb


on cool motor, remove fuel line to throttle body, turn switch to accessory position fuel should flow freely. no flow check filter located on frame rail. or defective fuel pump. pressure should be(if checked with good guage)45-55 psi. if all checks out throttle body jet clogged with gunk or you have broken-damaged throttle body wires. all of this i have found on 2.8 liter engines.-------jawstech goodluck hope this helps.

Truck doesnt start in the morning or after long periods of sitting. I have 40 lbs fuel pressure on the rail with key on and 60 while running. pour in a little gas in the throttle body and it starts right...


you should have 60 -66 psi there is a updated fuel pump with a new connector to splice in i would buy a ac delco pump and make sure you check the fuel filter first and if it does end up being the pump its a good habit to but a new fuel filter with it.

I have an 1997 tahoe and fuel pump went out replaced pump and filter and still won't start. gas is up on the rail at 45psi but not getting to the injectors


This truck requires 51-56 PSI fuel pressure before it will start.You may have gotten a bad fuel pump.

It will not start with low fuel pressure. Buy a bottle of quik start and spray a little bit into the throttle body (JUST A LITTLE BIT ) if it starts and stays running you have a bad fuel pump or a clogged filter. It is no reccommended to use quik start so only do this once or twice then repair the problem.

My truck will not start just cranks but will not fire


Air - not likely the problem ! mechanical cable controlled throttle body

Fuel- make sure there is gas in tank! fuel pressure test at the throttle body or rails, if no fuel check power to fuel pump: ignition power to breaker or fuse, relay , power to pump at 3 pin connector near tank/frame rail on drivers side, - if pump is runniig but insufficient pressure, check for mechanical restriction: plugged filter broken or pinched line, plugged pickup tube in tank. if good pressure to rail or body, check ecm : diagnostic codes, fused power, ecm tells injectors when to open, dependent upon several sensor parameter inputs.

Spark- ignition - coil-distributor-ignition module (or coil packs)- wires-plugs-ignition module (signals coil to discharge, mounted beneath distr cap) work backwards from plugs.

Throttle body injectors won't fire No


Check fuel filter and fuel rail. If there is fuel in the rail, and the filter is good, could be low pump pressure or bad signal from computer.

HARD STARTING ONLY WHEN WARM


Drive this thing until hot and when you shut it off, open the hood and find the vacuum hose that goes to the fuel pressure regulator. It will be on the drivers side of engine on the fuel rail. It's a little round vacuum diaphragm with a hose to it. Pull this hose off and see if gas leaks out the little nipple of the regulator. I'll bet it's leaking and what is happening is that it's flooding out the engine after it's off for an hour or more. These are fairly easy to replace since they are on the outside of plenum. Just be VERY careful as to look at the new one before removing the old one. Check location of the retainer clip, if it is not on right the regulator can pop out and you will have a major leak!!! Also be sure to remove the old O-ring and screen from the rail, they tend to stay in there when you pull the regulator off. You won't be able to get new one in if old parts are left in the rail.
