Varnished gas can cause this problem, its the case where the fuel sits a while and starts to change states from a liquid to a more solidified substance. theirs several additives that will help you for example (M2616
Engine Tune-Up
- Removes gum, varnish, and carbon from internal engine parts.) Anny cleaner that you add to the fuel that claims to remove varnish will be good. and should be a fairly cheap fix, good luck with it.

here is a site to gte info about the cleaner

please note: thewir are several types to chose from.

Wont start has new fuel pump and starter turns over fine going down the road and it spudders like it ran out of gas it just turns over not even trying to start


my 1988 towncar used to stop running on the open road at 70 mph after 20-25 miles of driving.......after sitting on the side for a 1/2 hr it was start right back up like nothing happened. After 2 frustrating weeks and 3 different mechanics I found out through another towncar owner that the ignition coil is getting hot and is causing the engine to shut off...Lo and behold 28.00 and 20 mins solved the problem. Just invest in a good Ignition coil from NAPA or SUMMIT PARTS

Why won't my miss fire?


Fuel injectors may be dirty.. or plugged. The car just sitting there may have caused the gas to go bad which may have given them a head start on plugging from the get go. Get some cleaner for it.
When the dash lights blink, is it unlike anything you've seen it do before?

Chrysler Intermittent Starting Problem


I have the same problem with my 2004 Chrsyler Concorde, however mine didn't start doing this until a recall involving reprogramming the cam shaft sensor was done. But I have exact same issues and no trouble codes appear for dealer either. My guess is that it is the cam shaft sensor, which I am going to get replaced. If you solve yours first, please post and let me know.

My 2002 Volvo S60 (non-turbo) has been sitting in the garage for about a 2 weeks. I started it one time during this period and no problems. This morning it would crank ok, but would not start. Any...


Two things come to mind First is take car needs 9.6 volts to start,place on charger for awhile then try again, thats a constent 9.6 volts sitting can dicharge the battery just enough for no start.2nd make sure you move the gas pedal alittle when starting. If these dont work for you repost and I can give you more Ideas

Jeep sat for 3 weeks in florida heat then went to start it and caranks but won't turn over. changed rotor and cap and coil does exactly same thing. also tried dry gas and put some high test in, but still...


you say it cranks but won't turn over they are the same thing,but no 3 weeks would not gum up the fuel,but the florida heat could knock out the electronics.

Ford F450 motorhome will not start


It may be the evap system. Could be as simple as the gas cap. try taking the gas cap off and starting it. If it starts then its the gas cap causing a vacuum. if not, then it could be:

1. Fuel filter.

2. Fuel pump. undo the fuel pipe into the engine and check to see if fuel is being pumped. disconnect the coil lead so engine doesn't start. Be very careful and make sure you put a container to capture the fuel.

3. If fuel is being pumped, then it could be the purge valve and/or vapor cannister. If these are faulty, it could cause a vacuum and vapor lock.

frankly, the fuel system isn't something you want to mess with if you are not a qualified mechanic.

try these easy forms of diagnosis to see if the gas cap is causing a vacuum, or if your brave enough, try the to see if the fuel is being pumped into the engine.

Good luck

Audi engine oil leak?


Sounds like a leaking valve cover gasket. The parts are around $50 to do both cylinder heads from www.ecstuning.com. It's not a major issue, but it may be a sore point to a potential buyer.
