Could be spark plug fouling by improper fuel flow...Clean or Replace the spark plug...Review the E3 plug availability for your model...Hope this helps.

    The choke needs to be fully operational (closed) to regulate the mix of cold air and fuel...does your system have a fuel primer?

  • rich Apr 22, 2013

    There is no primer the choke does close all the way. With it not trying to start with starting fluid I was thinking it was carb?

SOURCE: Ran out of gas and now she won't run!

i would say that you have a bad fuel pump or if you have a carb on it the float inside the carb is stuck check these and i'm sure you will find it's one of these.

i see, we ask for help and you want to charge us for it. But if we have solved the problem, you want us to tell you how we did it. Well my time is valuable too, i figure it took me about three hours to figure out the problem and fix it, at my hourly rate of $100 an hour, yes i am a business executive that works on his own cars, it will cost you $300 for the answer.

if you can hear the fuel pump when turn the key on with out turning the engine, then it could be that your fuel pressure regulator is broken, check your fuel pressur.

SOURCE: 1998 dodge ram 5.2. ran fine last night, today

Check fuel pressure, had this problem a year ago, bet the fuel pump is gone you should be able to hear the pump come on when you turn the key forward. You should hear it hum if not its dead, costly repair the pump,regulator and filt is all one unit.

SOURCE: 1995 chevy g 20 va 5.7 engine runs rough even

You may have picked up some debris and/or water when it ran out of gas. That got sucked up into the filter. Try changing the fuel filter I believe it's located on the right side, just ahead of the rear wheel.
Try that and see if there's any improvment. Hope this helps.
Good luck.

I have a Kohler 12.5 KW marine generator on my houseboat that has a problem I was hoping you could help me with. Specs: Kohler 12.5 KW 79 CID 23HP Mfg date 9-10-96 Gen Engine Serial # 06919 L-29-R

there are some magnets behind the flywheel to cause the battery charging system to recharge the batt. sometimes they come unbonded/loose from the flywheel and cause the engine to become hard to turn. I would start there first.

My 1996 Cadillac Deville takes too long to start if it hasn't ran for a while, and when it does start, it runs rough for at least 15 seconds.

Check fuel pump & pressure,may be failing

Have you worked on the car at all, in the last couple
years, or just driven it,that could be a factor also

Ford 1981 f 150 not running changed Coil distributor cap Roar arm plug wires did not help started bur ran extremely rough then died

motors need 3 things to run properly. gas spark and compression. the starting point. also spark timing.
the motor you are dealing with is easy. i just rebult a 1978. anyways sounds like a timing problem . first i would check the distributer. if all is ok spay a squirt of starting fluid in the air filter, or even wd40.,,,,,,,see if it is gasoline problem. isolate where the problem is.

Wont start 1995 bmw 525. just stopped on me pushed out of road day later it started and ran fine for 15 min. now it wont start unless it sits for a few days and is cool outside. when it starts last few...

next time it wont start, spray some starter fluid into the air intake on the engine, if it fires then you have spark, if not.....prolly a spark issue.

Recently bought a 97 wrangler, it ran a little rough when i first started it but only for about 15 or 20 seconds so i tryed to tune it up. replaced the plugs and plug wires and cap. now it sounds worse...

You better check the wires going to the plugs, is sounds like you may have got them switched aroung. Make sure you have the proper firing order it should be stamped on the top of the intake
