cranks but wont start

[bummie]

New to forum, any help appreciated 2002 explorer cranks but will not start, has fuel pressure (60 psi) and has compression (140 psi). No spark, but does have power to coil. Interior door lights flashed on when hitting the brakes when last running. Could this be a pats issue or gem module? Thanks in advance for any and all help

In past posts it seems that PATs issues don't even allow the car to crank.

Power to coil, but do the plugs have spark?

 

[TechGuru]

Don't the crank position sensor tell the ECU when to have the coil send sparks?

I am having the same problem with my 2002. was running fine then shut off in parking lot. cranks but not starting, will run off starting fluid so i put in a new fuel pump. still not starting! Changed out idle air control valve and have a fuel tank pressure sensor and temp sending unit coming Saturday. I also reset the roll over switch for the fuel pump and heard an audible click, but still not starting. It has a fuel filter that is less than a year old. Anyone else have any ideas?

Fuel pump fuse? Did you verify the fuel pump runs before/after replacing it?

I did plug in the pump while the tank was on the ground and could hear a faint hum. before reinstalling the tank.

I can hear an audible click under the hood when i turn the key on.

If the pump is running and no start but does start with starting fluid then I would look at power to injectors.

Check fuses 39 and 26

39 is showing 12.4, 26 is showing 0

And both fuses looked good

I want to make sure is it the fuses under relay box under hood or driver fuse panel? because i gave you the the relay box fuses.

 

[john gillenwater]

i printed out the pages from the 2002 owners manual. so i can check both fuse panels.

Disregard I saw the under hood box.

Changes out the relay hoping to get power to fuse 26 but still nothing.cant figure out why I'm not getting power to it.

I'm going to loosen the straps to make sure the short connector didn't come loose during fuel tank install.

Also noticed my fuel gauge isn't showing any fuel but I fills it with about 8 gallons. Pretty sure because I isnt getting power.

I replaced the crank sensor on mine and it started right up

I have an 03 explorer that also has crank but no start. I've replaced coil pack, plugs, tps,cleaned maf, cps. Checked fuel pressure 62psi. Checked fuses and relays. not getting any codes only live data. I know last time I had the codes read it said it was misfiring in cylinders 4 5 6 and when I changed plugs I noticed that bank 1 was dry and bank 2 was soaked with gas. I'm stumped on where to go from here. Should I change cam sensor or is it the pcm.

I'm thinking you have the 4.0,I would be looking at spark, if the plugs are wet from gas may have a bad coil. the aftermarket coil packs have been known to have issues....
