Without being there...its difficult to diagnose...but....( just a shot in the dark) When you first crank it up, there is a cold start injector that sort of adds an extra shot of gas to help get it warmed up...then, it cycles off, perhaps answering the run ok when cold. Now....perhaps when engine begins to warm....this causes metal to "expand" allowing for a vacuum leak somewhere. Listen for an unusually loud hiss, or air being sucked in somewhere. All internal combustion engines produce vacuum when running, as the pistons...on the down stroke create this naturally. So....when a vacuum hose, connector, intake gasket (where intake mates to engine or any device mounted to the intake) comes loose, breaks, wears have a vacuum leak that can cause engine to run poorly, or not at all. Also check for a egr valve stuck open.


Try to post back and let me know If I helped you solve your problem. It will help me with my rating....! Thanks

1975 Datsun (ie. mechanical fuel pump). Carburettor, electrics (inc. battery all good) fuel strainer all good. On cold start engine needs to be cranked several times. Warm start is invariably immediate. ...

Carburated vehicles ether have an automatic choke, or the very old ones, a hand choke. Yours has an automatic choke. The starting problem likely is a problem with the choke. The problem is almost certainly not the fuel pump.To set the automatic choke, push the accelerator to the floor, and RELEASE. Then start the engine just like you would a fuel injected vehicle. If this doesn't solve the problem, then the automatic choke needs to be repaired.

7.3 rough idle

Gas or diesel having same problem, I'd start there to confirm fuel pressure . It may be pump running partially when cool, but when it heats up (the pump) it may be cutting out pressure wise. Not uncommon for a fuel pump to pump good when cold, then die once pump heats up from running. Still makes noise, but isn't supplying any or enough pressure.

My 1980 toyota p/u starts idles but on the freeway it starts to die if you give it more gas it sounds like not enough fuel is getting to the carb when i let of the gas it seems ok until you start ta go...

i guess it has carbs on that year, which means
1.your main jet is blocked or
2. fuel filter is clogged,
3. fuel pump worn out
4.blocked fuel line
you simply have just enough gas to idle but when you demand more there just is not enough,

Has a hard time starting. Seems like no gas

"Seems" is a bad word when doing testing...You need real pressure tests done with a gauge attached to the fuel rail. I hope you kept the pump submerged in fuel when you ran it off the battery...they will quickly fail if run without cooling and lubrication provided by fuel ...many failures can be traced to running tank low a lot or running out of fuel for that very reason (also dangerous...spark near fuel can start a fire!!! )

1983 Ford F250 will start but won't idle without holding down gas

hi! there, its really help good of replacing old ones,perhaps the condition of current flow to ignite continously your combustion due insuffcient current supply from your ignition system could positively stop your engine,if you maintain this ignition system the engine won't stop such a case this type of model need mostly to be tune up some internal part on the head cylinder should take place of correctnes such as intake and exhaust valve,the rocker arm seat valve and spurk plug.if you done this your worry will be lessen.have a nice day.

My 92 Bird with the 3.1 did the same thing after it sat for about 2 months. The car had aways started right away before. I had to jump start it and I thought it would never start.Same as yours after it started. Seem to get better after I ran it awhile. It was getting good spark and was getting fuel. I checked fuel pressure, it seemed to be within specs.then it started to sputter and the pressure dropped to almost nothing. Seems that the fuel pump was going bad, but still would pump enough fuel at times to run. When the car was parked the fuel pressure would bleed off, and when I tried to start it the pump had trouble pumping enough fuel to pressure the system.Long story short! Replace the fuel pump, and filter.....
