2002 Ford Taurus won't start after driving Sign In

Year 2002
Ford
Taurus SES
3.0 V6
134813 mi/ 216960 km
After driving my car (usually for half an hour) and letting it sit for ten minutes to a few hours it won't start for 5 minutes to fifteen minutes. The engine cranks but won't turn over. It always starts first time driving it in a day but not always after I drove it. It's a very common problem but I can never replicate it when I take it in. It's had some idling problems in the past too with the belt snapping and rarely dying at stop lights. Hasn't done that in a long time. Any help is much appreciated thanks.

All we can do it tell you how to test for the problem.


All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.



Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Unfortunately on this one, there is no one common "smoking gun" for this problem....

HT has posted a very detailed flow chart to find the exact area of the problem....

If you are diag'ing this yourself at a bare minimum you are going to have to find out if it's losing spark or fuel (while the problem is happening) to go any further..

On a side note....That was a very detailed and concise post.....right to the point and crystal clear on the problem.....I'd give it a 9
