So the truck cranks but it won't start? do all your basic checks check for spark, check for fuel or compression. Make it simple the gauges and all the indicators could be irrelevant to your no start

Yes it cranks but won't run, I know its not getting fuel because it won't turn on the fuel pump, which is brand new.... im just going off the gauges because im getting no oil pressure, no voltage read outs and when i turn the key it isn't turning on the fuel pump thats why im thinking its ignition related, i could be wrong, have been before, but its acting like its electrical

doesn't a relay trigger all that.

 

what is underhood stuff doing.. does the fuse block smell bad?

 

I have a 96. Been all over everything learning stuff.

my only quibble was realizing 40 amps in parking lights...swapped it all to led, including the dash.

 

quite a big load.

 

I am interested in the resolve. that much stuff not coming on should lead (pun) to a big power source as the error.

Ok so made progress today, it looks like it's the ignition starter switch, which is the black plastic box under the ignition switch on the column.... I removed it to see what it did and all the lights on the gauges and all the read outs are working now plus the fuel pump is coming on now... Now the only probably is that it won't run still, I'll get a new starter switch in and see if it is all fixed

      Gas Prices

      Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way too big headlights (similar to a previous non-Wrangler SUV) should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crossing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...
