I would have the cooling fan checked, and have the thermostat changed. An overheated thermostat (overheating caused by something else) will cause problems in the future.

Fuses are located by the side of the dash board when you open the driver's door. The fuel pump fuse is situated in there.

try another dealer. maybe try to get ahold of one of the techs at lunch time. this info should be free to the car owner, just be ready to supply the title to the car for some proof. maybe try buying the parts guys lunch or coffee and donuts....this usually works for this type of problem. unfortunaley this info really is dealer only..

I need to read codes

Are you fully obd1 compliant? If so, you should be able to use jumper wire at A & B terminals of your data link connector. Then turn key just till the dash lites come on, the cel starts flashing, you count the flashes to get the code, two digit number.
On older vehicles, sometimes the cel no longer works, for whatever reason. On those vehicles I use a scanner that will show live engine data, try to see if anything doesn't look correct. Just my opinion.

2003 jag s wont start, hit in rear panel, no rear damage, nersha switch to trip was re-set.Door, lights work- windows d/n roll up/down-cannot shift out of automatic.Steering wheel,ignition key turns

Hello Margaret,

From what I gather, at a certain g-force deceleration (collision) this switch (the inertia safety switch) is tripped shutting off the fuel pump.
I have also read that even when the inertia switch is tripped in a accident, the fuel pump sometimes will still function normally.

If your vehicle s a North American model the first place to start is a code scanner to see if any fault codes have been logged.

'Regular' OBDII scanners will only capture engine and transmission codes, all other advanced systems like ABS, air bags, body modules, etc will require a more significant software/scanner. Right now the autoenginuity scanner is currently the most affordable and effective scanner for the jags standard and enhanced codes.

If your inertia switch has been re-set I have read in some blogs that disconnecting the battery will sometimes clear up unusual conditions.

Check engine

Your Rodeo's onboard computer has detected an error in one or more of the many systems on modern vehicles. Along with the Check Engine light on your dash panel, the computer has recorded a Diagnostic Trouble Code (DTC) that can be read (and cleared) by a code scanner. Large auto parts stores usually have code scanners that they will allow you to use - normally at no charge - at their location (a good store counterman will even connect the scanner, read and interpret the code, and advise you of the problem and possible solution (they are trying to sell you parts, right?). Some error codes are advisory and inconsequential, while others indicate serious problems that should be corrected immediately. Go have the code read and interpreted, then decide if you want to have it resolved soon, immediately, or sometime before your next vehicle inspection. Good luck.

Town Car 2004 wont start on first try

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

I have a 1995 dodge neon 5 speed manual and right when I start the engine my check engine light goes on and autozone check the codes and it read u3fff can you tell what this code means for my car cause it...

Thats not a valid obdII code. Thats actually an error from the scanner itself not understanding the data that was sent.. I would clear the code and see if it returns. If it does find someone with the proper code scanner for a CAN system.

For a couple of days now it had a long crank then it would start. today the check engine light came on but showed no malfunction i then tried to start it after a while of being off and it would only crank...

You need to read the computer codes with a rented scanner and follow the clues. These codes can point to specific parts or sometimes just general areas. When the problems are repaired, the scanner can clear the light. Good luck!
