NC Tom Posted April 22, 2023 Share Posted April 22, 2023 See pic. It the belt supposed to be touching here? If not, how do I adjust it? Link to comment Share on other sites More sharing options...
AZJeff Posted April 23, 2023 Share Posted April 23, 2023 No, it’s not supposed to touch. I don’t have the routing diagram so I can post it from my iPad, but someone can chime in with it, I am sure. if you do not have AC, do you have the AC delete pulley installed?

Is it possible that my power steering is too high? I had that replaced a few years ago. Hard to believe it would move. Also, when I press down on the belt belt, how much deflection should there be? And should the AC compressor move when pressing belt? Link to comment Share on other sites More sharing options...

cruiser54 Posted April 23, 2023 Share Posted April 23, 2023 The idler should NOT move like that. Nice graphic BTW! Link to comment Share on other sites More sharing options...

Not sure why it's moving, but I'll look into it. I "fixed" the leak at the front fuel rail, but still no start. Fuel pressure is good while cranking, but once you stop it drops straight to zero. Is that normal? Should pressure stay up while key is "on"? Also, my battery is weak from all the tries. It's charging now, but can a weak battery play onto this? I bought that Noid Light kit as suggested by @ratrapp, but I need to read how to use the dang thing. While I'm learning a lot, I am not happy at all about how much time this is taking.

ratrapp Posted April 23, 2023 Share Posted April 23, 2023 to use the noid light all you have to do is unplug 1 injector and plug the correct noid light into the harness and have someone crank it.it should pulse to let you know the ecm is commanding the injectors to pulse.did you pull all plugs to verify theyre not gas soaked?also you should be able to hold fuel pressure for a while.thats saying if it drops immediatley then you can either have a stuck open injector,bad regulator or there is a leak inside your fuel pump assembly from where the hose connectors to the hanger or ive even seen the pump itself leak where the pump body is assembled.

I've only pulled one plug. Will pull them all now. Is there a test for the regulator? Link to comment Share on other sites More sharing options...
ratrapp Posted April 23, 2023 Share Posted April 23, 2023 usually if theyre going bad youll see gas coming out of the nipple that the vacuum hose attatchs to.it can also be bad and fuel not coming out of the nipple as well.you would have to remove the regulator and fab up a block off plug to eliminate the regulator and start narrowing down if you have either a stuck injector or a leaking pump.if any plugs are fuel soaked then that may be signs of a stuck injector.

ratrapp Posted April 23, 2023 Share Posted April 23, 2023 thats a good sign.if all the plugs look good and your sure your getting spark then spray a small and i do mean small amount of carb cleaner in each spark plug hole,reinstall the plugs and see if it starts or try to start.

ratrapp Posted April 23, 2023 Share Posted April 23, 2023 i do stress a very small amount of carb cleaner.I'm talking like the amount that comes out of those battery powered air fresheners.too much will either flood or hydrolock the engine.

ratrapp Posted April 23, 2023 Share Posted April 23, 2023 have you checked under the distrbutor cap to make sure that the rotor button hasnt come off the shaft.ive seen that before as well. Link to comment Share on other sites More sharing options...

Not yet. Based on this first plug, I'm going to replace them all. Link to comment Share on other sites More sharing options...
ratrapp Posted April 23, 2023 Share Posted April 23, 2023 just get a cheap set of copper plugs to get it running.it doesnt need or will benefit from platinum or iridium plugs the stores will try to sell you.try new plugs before you spray carb cleaner in the holes.this is just a test eliminate that you don't have fuel on the plugs to combust.

That looks like one of those fancy Iridium or Platinum tipped plugs. The 4.0 doesn't benefit from them in the slightest, and may actually run worse, since they lack the extremely high voltages needed to jump that type of gap reliably. Put in some good old fashioned conventional plugs (Champions were OEM.) Link to comment Share on other sites More sharing options...

The graphic I did because I needed to do something fun amidst all this stress! If the pulley on the compressor is moving, it is probably due to a worn out bearing in the compressor clutch hub. This can be confirmed by removing the belt, and turning the compressor pulley by hand. It should spring smoothly/freely, with no noise. If it is determined to be bad, a replacement bearing can be had from Rock Auto pretty reasonably. Link to comment Share on other sites More sharing options...

New plugs installed, still no start. Haven't checked distro yet. But, I noticed I a nipple without a hose attached. See pic. Should there be a hose there?
