Question about 1995 Jeep Grand Cherokee
I have a 1995 Jeep Grand Cherokee Laredo. I replaced the crankshaft censor, the camshaft sensor, and removed the alarm system module. It will not start. I also replaced the distributor cap rotor etc. Any suggestions as to why it will still not start?
Dont just replace parts and hope--u must target the area--a data stream run w factory gear is really helpful--a code reader is usually not enough-----the module u took out is connected to ignition----inspect coil-plug wires--ignition module--distributer cap may be worn inside--look for any loose wiring in engine area----may need a fuel pressure test--regulator and pump cud be worn---basic spark and fuel hardware are the weakest links

1) Remove the driver door panel 2) Remove the lock 3) Remove the switch from the back of the lock 4) Pull the switch cord assembly to the bottom of the door cavity 5) Unplug and remove the switch assembly from the car 6) Either (a) short the female end of the plug, or (b) ground the striped wire to the car door.
Normally, you would insert the key in the drivers door, turn left, then right to disarm and reset it. If yours is malfunctioning, you can disable it for good by doing the following:
The FACTORY ALARM DISARM WIRE IS purple/yellow |-| in the driver kick panel area, at the black plug.
Once Located, splice into this wire with a simular guage wire, and put it to a solid chassis ground. This terminates the alarm functions entirely.
Go to the passenger side door and lock/unlock 2 or 3 times to deactivate the alarm switch in the door latch. If battery is weak/low it wont solve problem, must replace battery.also check for broken hood pin switch($5.00) as they are likely to be broken on a 94 veh. and when failed will cause security system to activate causing security light on dash and no start condition/lights flashing etc

First, nothing you have done has anything to do with valve tappet noise. What is your oil pressure? Have you positively identified the noise as a lifter (tappet), OR COULD IT BE AN ENGINE BERARING OR WRISTPIN? Other than tearing it down and replacing lifters, rockers or pushrods or possibly even the cam, if oil pressure is good, change the oil and put a quart of Marvel oil in there. If that does not clear it up in a few days, you will have to go inside the engine. You likely have over 160k on that engine...consider using a replacement. Get an older tech to listen to it...it takes years to be able to differentiate between different component noises with any accuracy.
Personally, without hearing it myself, I'm betting it's a rod knock.

SOURCE: problems starting engine.
If your engine is turning over, but not starting, then the alarm is not the issue. The alarm will keep the vehicle from ever cranking to begin with. I don't believe that jeep used any type of immobilizer system back in 1995, so that should rule that out of the equation. You sound like you have some mechanical aptitude, and at least you know that it's missing spark, and where it's missing it at. Your next step would be to find a wiring diagram of your vehicle, and sorta trace the current flow backwards and find out exactly you're losing it at. Chances are it's something stupid simple, but you're just gonna have to do a little current tracing and check each connector, relay, fuse, etc along the way with anything involved in that circuit.
