Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hi Welcome to Just Answer! Which engine do you have in your aspen and what does it do if anything when you try to start it?
so the engine cranks but doesn't start?
ok it could be a few things. Fuel pump and crank position sensor are the most common issues.
which engine do you have and how many miles are on it?
Have you replaced the cam shaft position sensor yet?
ok just to make sure what you have done so far you have replaced the fuel pump, both the cam shaft and crankshaft position sensors?
ok have you doubled checked the fuel pressure at the engine you should have around 45 psi
You will need a fuel pressure gage and a pressure t to hook the gage up
you really need a gage to check the proper fuel pressure the only other thing you can do is take the fuel line off at the fuel rail and put it in a container and see if it pumps fuel when you turn it to the run position
it could be a timing issue or a computer issue also
if you have fuel the next step would be check the computer with a scan tool
to check the timing you will need to remove the valve covers to check the cam positions in relation to the crank shaft position. The scan tool would allow you to check codes to see if anything is preventing it from starting
Please let me know if you need any more help with this issue
