Question about 1990 Dodge W150

1 Answer

Will start every time ....but wont stay running

This truck was purchased as a plow truck. It is a half ton 4x4 with a 318 motor and I believe fuel injected throttle body. I knew it had many issues but had driven it before buying and seemed to run "ok" then. The issues were poor brakes, exhaust, power steering problems and some others. I can deal with those one at atime but the truck wont stay running. It will start up with no problem. It will run for 5 to 10 seconds or so then die. Try to start again and starts right up but wont stay running. When running engine sounds like it is strong. I have found fuel in oil which indicates flooding. I have done all the simple things...new plugs, Dist. cap, rotor, wires, fuel filter, oil change, etc. I know there are many things it could be but wondered if their are ones that are common with this model and year? Some casual comments have been.... Throttle position sensor? Temp sensor, fuel pump, fuel pump regulator. There seemed to be vac lines that are capped off and other wires that are disconnected.....I assume some of the emissions stuff is not operational. I am hoping to at least get this truck running and idling and then take on the other issues as I can afford. Thanks,

Just ashot in the dark while under the hood rev youre throttle up ,at the same time watch youre damper if it skips or rolls back it needs replaced .it controls your timing . this part can be recked by over reving to much strain put on your engine and doesnt go qiuckly it slowly gets worse and so long as you dont fix it you timing is allover no matter what untill its repairedalso further abuse and it can steretch your timing chain.your 318 1990-93 throttle body injected engine only has 144 horses and 288pnds of torque its pulling rating is based on its incredeble suspension system . and lets asume the person who told you about the throttle position sensor is not the same thing as your air idle control acrtuator wich is attached to your throttle cable which you should never mess with but if it is all loose and sloppy replace it set the screw so youre vehicle rpms are between 2500rpms -2900rpms the sounds of your truck its been abused before you had it.this part has to be analogicly installed buy adodge repair book by haynes and you can save over 1000.00 on this repair alone its very detailed.good luck

I can hear my fisher plow motor but the plow will not lift or angle


There solinoids on pump. Check wiring and grounds. Make sure all small wires are intact and in good condition. But most likely there's a loose corroded or green wire causing issue

It may be a temperature sensor. You might have two,one for the computer, and one for the light or gauge. If the one for the computer is bad, it might think it's cold, and it will dump more fuel. On some GM models, applying the throttle will reduce fuel. You will need a scanner to verify this.

Battery Not charging


I believe I can help you. There are a few things to check.

First, are you running the plow a lot when you're having these problems? If so, you MAY need to install a second battery designated for just using the plow with it's own alternator. Hydraulic pumps use a lot of electricity to run.

Second, there may be a short in your electrical system, try installing a battery disconnect and disconnect the battery every time you shut the truck off for extended periods of time (more than a day).

Finally, check the voltage regulator (or have a shop look at it). If it is not working properly, the batteries may not re-charge correctly. The cheapest way to solve the problem is with a battery disconnect, but it may get annoying after a while, especially if you forget to disconnect it and your battery goes dead. Finding a short in an electrical system is a long and tedious process that may not always solve the problem. And installing a second battery and alternator for the plow can get expensive.

I hope I could help you with your problem and good luck.

Battey wont charge


may have a short somewhere but check the ground cable/ connections first, there will also be a ground from the engine block to the firewall if you cant find it attach a new one (don't use thin wire or it can melt) dosen't matter where you put it just as long as it gets a good connection at the block and firewall(no painted surfaces/use sandpaper)
