hello my name is ***** ***** for using JA i will be happy to assist u today. have u tried priming the the fuel filter pump on the top of the filter housing to see if it will start, prime it 10 times or so then see if it will start
what was the code number that was in it?
do u have a scan tool that u are using?
ok, those are both for exhaust temp sensors, shouldnt cause a no start at this point further tests will need to be performed.
1. Using a noid light, check for injector pulse during cranking.2. If present, check the return rate of each injector. For a 15 second crank time, the return rate should be 3mL per injector.3. If not, check for debris or clogged injectors.
ok no problem, another thing to check,
on your scan tool.
1. Check the scan tool data list for "CAM Signal Present" and "CKP Signal Present".2. If both read "Yes", check the Desired and Actual Fuel Rail Pressure while cranking.3. If the Actual Fuel Rail Pressure is low, prime the fuel system. Check the crank Actual Fuel Rail Pressure.4. If the Actual Fuel Rail Pressure is low, check for fuel flow from the Fuel Pressure Relief Valve.5. If no fuel is leaking from the Relief Valve, check the fuel injector return rate.
ok that is a body control module code, sounds like there is a communications problem, there will be some in depth diagnosing going on here are u planning on attempting yourself?
ok, like i said it could be a lot of issues causing this problem, sounds like its a communication issue, it could be a crank sensor issue, it could be a injection pump going bad, without proper diagnosing it is very hard at this point to determine the exact issue u have, especially since u do not have proper diagnosing tools to go any further, i would condem the crank sensor or the injection pump or a power or ground problem with the computer. but at this point its very hard to diagnose without the proper equipment, u may need to have the vehicle towed at this point.
