MY 2004 FORD RANGER D/CAB TENDS TO THROW THE BACK OUT EVEN ON ROUGH TAR SURFACES. HAVE HAD SHOCKS TESTED - OK. IS THE PROBLEMS TYRES OR SHOCKS?

SOURCE: Truck Won't Start At All

before replacing the starter get a volt meter and test the voltage coming out of the voltage regulator which the power comes from the battery to the regulator down to the starter also make sure all wires on the starter are clean and what I mean is from rust because I had an f150 that did the same thing

I would check your crankshaft positing sensor this may be bad. I would also change your spark plugs and wires becuase they may have got water in them causing a short between them and the head. I would very carefully use air to clean the dirt from your engine compartment first. Autozone runs a free code check for you and this will tell you your problem. To clear your codes and to make the check engine light go off take off your battery cables and wait 30 minutes. You may also have a bad coil which will cause a misfire as well and a 306 error means a misfire to your 6th cylinder so it's probaly this. I hope this information helps.

WOW that is strange. Get your self a test light or a cheap multimeter. Take the + wire off at the wiper motor and check if you have voltage / power. If you do then the problem is with the wiper motor if you don't it is the wiring or the switch. I know, not a complete solution but it cuts your problem in half :)

Good Luck

You may have a bad idle control valve. If you want to replace fuel pump yourself you will have to remove bed of truck or fuel tank.
