Question about 1985 Ford F150

1 Answer

Will not start

I started out by adjusting the idle on my carbutor and then I changed out my cap & rotor, after that it would not start. It has a fully charged battery. Is there some way I could had disconnected a wire or wires. I took off two different spark plug wires and checked for spark and did not have any. I then did the same with the coil. Because of the depth of the spark plug boot I also tried putting a nail in there and grounding it to the block. Still no spark. Also going to my carburetor is a lot of electrical wires that look like they go to a solenoid. It has a rod that comes out by the idle screw and looks like it affects the idle. Could this have anything to do with it not starting? It was starting and running find before.

    You have probably touched something and blown a fuse. You are going to need a test light at the very least. Go and buy one if you don't have one. Check for power on the positive side of the coil with the ignition on, if you don't have it, check all the fuses. If there is power there, have someone crank it over while you check the negative side of the coil, the light should flash while cranking, if not, you may have a bad module.

Your ignition relay could be bad, there are fuses and relays that feed power to the distributor, easiest way to find them would be to follow the battery leads from the battery to the coil and cap, check all the inline fuses and relays/solenoid

Check your set screw, and make sure it's not too low. Adjust the screw to the point that where it idles at the proper speed. Also, maybe check your throttle cable for too much slack.

1988 GMC pickup 4x4 350 engine its hard starting and will not idle i gave it a full tune up even a new fuel filter ive checked and changed all sencors on the motor

Do a compression test. The pistons and rings may not seal enough anymore. Try push-starting it in 2nd gear. When you push it ,it will turn the engine faster and build up more compression, enabling combustion to take place. Aslso check if the fuel pressure regulator is not leaking through the vacuum hose, causing it to flood.

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.

My car went from 30 miles a galllon to 20 miles a gallon it seems over nite

most likely suspect is the carb

However, I'd start with your basic tune-up first...
  • replace spark plugs
  • replace spark plug wires
  • replace Dist cap and rotor
  • replace fuel filter
  • replace air filter
  • change oil
  • adjust timing and base idle speed
  • adjust fuel mixture (if available)

96 tahoe won't start when cold unless you spray engine start into the throttle body intake. Once started it runs great and will restart as long as it is warm?

you need a new electrical choke, if you do not have one on the carbutor you can buy one and install it. it start the car right away at a high idle adjusting itself down to a low idle when the engine is warm. very cheap part. you will be very happy. no engine start to start your car.
