Being that this vehicle is a 1988 it is most likely still using an electric choke. When your vehicle is cold (even just not warm enough) it needs a richer fuel/air mixture to start which is what the choke is there for. When you turn the key the choke will automatically shut so the suction from the engine will pull fuel from all circuits of the carb. Anyways.. long story short for some reason it would seem your choke isnt closing as it should. This is generally just a hot wire thats connected to your carb.... maybe a short maybe its stuck open for some reason.. idk but that is where you should focus your attention. Hope this helps.

SOURCE: 1985 diesel after sitting overnight will not start

The check valve is a small brass fitting where the return line attaches to the filter head. I believe it takes a 7/16" wrench. There is a 'duck bill' inside that prevents fuel from leaking back to the tank causing air in the system. It should allow flow in only on direction. Some times you can see light through it if it's bad enough. Also, the lines between the injectors can dry out and start to leak air. Air will leak in before fuel leaks out, and you won't see it. There are plastic, cup-shaped connectors for these hoses that press onto the top of each injector. They are sealed by two o-rings on each injector body where it meets the connector. These o-rings can dry out and also leak air and fuel. Your Ford dealer or diesel service professional should have the proper o-rings. Any other o-rings might not seal, as they won't be the exact size. You already changed the fuel solenoid when you replaced the pump. It is inside. There has to be battery cranking voltage to it while cranking, and battery voltage with key in 'on' position. The wire attaches to the top of the pump. This is not likely to be the problem, since it restarts every 2 hours.

1992 Chevy Astro won't run, will start up great with starting fluid, or let it sit overnight.

You need to check the fuel pump pressure and I would change the fuel filter in the process. Sounds like you may have a bad fuel pump.

Electrical problems,won't start in morning after sitting overnight,with boost it starts immediately

Have your battery load tested at auto parts store. Do it while still in the car. They can also check your alternator at the same time. It sounds like you either have a short that is draining the battery as it sits overnight or as your vehicle runs the battery has enough charge to run but not enough charge to last it UNTILL the next morning.

Can anyone explain why my 1993 Cadillac Eldorado wont start after it sits overnight? Also, why does my interior lights jump on sometimes when I hit a bump then turn off when I hit the door panel. My car...

Cranks and starts are two different things.
If it cranks but won't start it could be loosing fuel pressure overnight.
If it won't crank in the morning, you could have a bad cell in the battery or something draining the battery overnight. Such as the interior lights coming on and off.
The light problem could be the door ajar sensor in the door latch.

When my 1988 toyota camry sits for a day or two without driving, the first initial start does not fire-up as I turn the key. I have to hold the key in the start position and the car will eventually start

All cars require a little priming. Try this, turn the key on, let it sit for about 30 seconds then try and start your car. When you first turn the key, the fuel pump will begin pushing fuel. My Mustang does the same thing when its been cold. Of course, in Tucson it does not get cold very often.

Have a 01 Tahoe with new red top and fairly new alternator. It charges at about 14v. But if I leave the Tahoe set for a week, it wont start.Where do I look for a voltage leak. The Tahoe seems to be working...

Start with the basics; Is the reason the car does not start is that the battery is discharged after a week of sitting or a case that it won't start without a jump although the battery is still good. If the car just does not start after sitting then try the following; Pull the negative battery cable and let the car sit overnight. Reconnect the cable in the morning and see if it starts. If it does then you are looking for something that is pulling current from the battery. Could be lots of things; light on in the glove box or trunk, a short in a wire, etc. You can try pulling a couple of fuses each evening and in the morning, replace the fuses and see if the car will start after sitting. If it continues to discharge the battery then try another set of fuses. The day it starts after sitting then you have narrowed the electrical system that is discharging your battery. Focus on those systems
