2010 CRV, just shy of 30,000 miles. Will not start. Has been in the repair shop 4 times in 7 or 8 months. New Alternator, new battery. What is causing this???


has there been any fault codes reported or has anybody bothered reading the fault codes
reasons for not starting include
cam/ crank position sensors--- broken wiring , faulty harness connections, sensor position adjustment incorrect
low fuel pressure --- pressure regulator problem, fuel pump relay problem, fuel pump
immobilizer problems --- fob battery low on charge , problem immobilizer system
ignition control module--- wiring , faulty internal components
gear position switch---park or neural out of adjustment--wiring problems
a battery may be causing the problem--- but check ground points for tight and clean-- if you are saying that occasionally it will not start, it could be a problem starter motor with a bad commutator bar
it has been back for a number of times but the replaced items indicate that the shop is using a replace parts to find the problem rather that a fault code systematic approach to trouble shooting and problem solving
might pay to find an accredited service shop with experience on your make of vehicle

What makes you think the computer is at fault ? Check power an grounds first , do you know what these are ? Go on youtube an check out videos on voltage drop testing .Also videos on basic electrical trouble shooting . How to read a wiring diagram . Then go to http://bbbind.com/free_tsb.html free wiring diagrams ! Test the main power an grounds , then have the vehicle checked for DTC'S - diagnostic trouble codes . Not just the PCM - engine computer but also the GEM - generic electronic module ,fords BCM . Also check battery an connections . You more then likely have a bad or corroded ground connection . Anti-theft system light on .

Running light problem on chevy express 3500 box van


Vehicle electric trouble shooting is the worst. Some of the problems you described the bulbs may have multiple filiments with only some burned out. It may sound silly but change the bulbs. Get a couple of new bulbs and try them in the different spots. Time, road vibrations and spring pressure causes the contacts on the bulbs to wear until they get a poor connection then you get a little arcing that build up a residue and a bulb that test good doesn't work.
Your on the right track with the ground wire. Try a test lamp with a good gound connection and test the different sockets, if your test light works but your bulb doesn't you have a ground fault. If neither work check the switch and fuse before you start tracing the wiring. These are just general trouble shooting tips It's very hard to trouble shoot electrical problems sight unseen.

Im having trouble wiring a back window to a bronco


You may have better luck putting two in-line blade fuses as a fault protector, only substitute the blade fuse with a circuit breaker. It sounds as though you know how to make it go up and down. Adding the circuit breaker to the ground and using a common ground on the switch may save a couple of dollars instead of two inline.

Trouble Shooting Codes


It sounds like the throttle position sensor (TPS) needs to be replaced. When the TPS sensor goes bad it will give you the codes you received.

Problems starting


sounds like you have a bad ground fault switch( safty switch). if you move the shifter around slightly while in park and have someone turn the switch will it start? that would indicate a short or a misalignment. Be sure to keep you foot on the brake anf have the parking brake set while trouble shooting. let me know MrRodneyLong@gmail.com
