This guy loves throwing parts at it instead of troubleshooting.......

 

^^ exactly

 

So what. Get over it. Two different types of people, part changers and trouble shooters, that's just the way it is.

BTW- If it matters I'd guess head gasket too, leak down test is probably what you want to do. It's easy and fast and then you'll have a major part to change :P FUN

 

I'm with you on that.

Don't give up on you Jeep. XJ's don't die, they just have fits.

 

ok so new starter on and plugs dist. cap and wires still does the same thing will not idle and a puff of white smoke comes out of my intake when tryin to start. any ideas of wat could be wrong now. also the red gen. light is now on what does this mean please help i need to get this thing fixed A.S.A.P.

 

That light usually mean you have a charging problem. Possibly a bad alternator. Did you ever do a leak down test?

 

i wonder if the sync module in the dist could be causing this any body ?

 

in the fsm for a 97 xj it state that the sync sensor sends a signal to the pcm when the injectors fire
maybe its going bad and causing the injectors to squirt late or early in the firing order hence the whit smoke coming out the air box thats going by all oter timing and fifring orders are correct

 

how do i do a leak down test and i just put a new battery and alternator on so should be no problem wit that stuff

 

Did you do a compression test?

 

So far you have replaced: TPS, CPS, IAC, Fuel Filter, Battery, Alternator, Plugs, Wires, Starter and Distributor Cap. You need to check your Compression and Fuel Pressure.

 

what he said.. before you put at more parts on it check those essential things

 

ok how do i check my fuel pressure?

 

A "leakdown" test is a differential cylinder pressure test. It requires a compression tester with two pressure gauges - one that shows how much pressure leaks out of a cylinder. One guage is used to maintain constant pressure, the other to measure how much "leaks down". While it is leaking, an ear to the exhaust pipe tells you if it is an exhaust valve. Listening to the intake tells you if it's an intake. Listening to the crankcase tells you if it's piston ring blowby. Once you know where the pressure leakage is occuring, you can fix that problem without throwing money at it. Or, better yet, you find out there is NO problem.

You put 80 pounds of pressure in the spark plug hole with the cylinder at TDC using the fittings supplied with the tool (they cost about $60 as I recall). You regulate the input pressure and measure the loss. If you have more than a 25% leakdown, corrective action MIGHT be required...but maybe not. 25% is the number they use for aircraft engines...obviously, a more important and critical use than jeeps...so maybe you can live with leakdown of 50%. I don't know that answer. I do know that you can do the test on each cylinder and isolate exactly where the leak is occuring, if there is a leak at all.

By a tester from Aircraft Supply in Lansing, MI. It'll have instructions on how to use it. Or, just cruise out to the local airfield and find an A&P (airframe & powerplant) mechanic - he'll have a tester and know exactly how to use it and it might be cheaper than buying one for a single use.

Good luck.

 

any ideas on why the puff of white smoke out of my intake when tryin to start?
