Question no this can't be happening

95 Ram 1500 5.9 efi gas engine.
Completed new engine install. Everything is connected and THEN (?)
Turn the key and check all guages, and temp guage shoots to 260 degrees.
Engine has not even fired up yet and guage reads 260.
Turn off the key and it drops to 0 degrees where it should be.
Engine cranks but wont start. Almost seems like no power to plugs.
New Accel mopar coil, new distributor and cap,new plug wires.
And full set of 8 Autolite XP3924 Iridium spark plugs.
All ignition conections with Dielectric lube.
New engine ground wires #8 wire from engine to firewall conections.
Where did i get messed up??

Get copper core spark plugs. These Trucks don't like fancy stuff. But that's trivial stuff

Need to verify you're getting spark to the cylinder.

Hear the fuel pump prime?

Proper wire routing?

Give us more detail on what you did exactly and why?

Not sure what problems you have had with your spark plugs.
But woud like to assure you i have used the XP Iridium in all my trucks.
Never had any problem with them. That big bright white/blue spark lights up that -50 degree fuel just like it should.
Never used the Copper ones, but no need to change these for another brand.
Replaced the temp sensor and fixed the temp issue.
Replaced the crankshaft sensor and sparrk is true blue.
Problem seems to be fuel is not gettin g into combustion chamber.
Fuel rail is presurized, but seems fuel injectors are not getting signal to charge cylinders with fuel...
Have not solved that issue yet.
Thanks..

Default Fuel not being injected into engine

95 Ram 1500 5.9 efi gas engine.
This is new engine, never been fired and after checking everything i can think of it is not getting fuel into the cylinders.
Fuel rail is charged with gas but seems injectors are not getting electric pulse to spray fuel ino chambers.
Injectors were all checked and tuned by quality performance tech before they were installed.
Is there a part of the electrical system for fuel injectors that i might have missed ???
Have several threads in non-tech section on this engine but no solution has been offered.
Really need serious advice to help me get this fixed.
Thank you..

Try looking here they have all kinds of diagrams.

This is the injector diagram.

Looks like the PCM controls the injectors.

Check your cam position sensor. (it's in the distributor) If it has failed, or, simply isn't hooked up, the PCM doesn't know which injector to fire, so it defaults to "none"......

Are you getting spark?

check the ground on the power steering pump. that will stop the injectors from firing too.

Distributor/cam sensor is hooked up properly.
How could i test it to see if its sending signal ?
Plenty of spark ..

Its just a hall effect switch. A scope would make it easy, but, not many folks have those at home.....

Getting any codes? The PCM should whine about no cam signal if it isn't getting one, and the motor turns several times. (according to the crank sensor....)

Old sensor, or new?

Every sensor on this engine is new OEM sensor.
Have great power to every plug and timing light.
