plymouth grand voyager electrical problems

I have a 2000 grand voyager heres the deal you turn the key to start it it cranks but dont start i dont hear the fuelpump.But when you let go of the key a relay under the hood keeps ticking until you pull the battery cable off i have replaced the ignition swtch but get the same thing Help im going nuts:banghead:

Post this in the Dodge forum for specific help.

I've moved this thread to the Caravan/Voyager forum.

There was a common issue that would cause stalling in some of these. I don't recall which model years or exactly what the cause was. I think it had something to do with the Auto Shutdown (ASD) relay. I think those issues also typically threw a diagnostic code.

Have you checked for current or pending diagnostic codes?

it does not have any codes we evean switched around the relays still the same problem no check engine light on either

i thank people for their replys any info helps at this point im going nuts

this van wont start it turns over but does not start or try to start now

Which engine? Engine cranks fine but won't start correct? The typical fault is a bad crank or cam sensor or associated connections/wiring. The PCM needs both signals to establish timing. If it doesn't see it it will crank all day, just won't start. They often fail without throwing a code. No spark and no voltage at the coil connector while cranking is one indicator. Next comes fuel. Depress the test port stem on the fuel rail. If fuel quirts you can assume there's good pressure. If it dribbles out you have a pump issue. Best test is with a pressure gauge. Should see 49 +/- 5 PSI.

Clicking relays are an indication of weak power either from a weak battery or poor connections in the circuit.
