My 2005 E-450 bus with 6 liter turbo diesel, would crank but not start. Found that there is a faulty connection somewhere on PCM, can push on connection and problem will go away for months, Did have to put a piece of aluminum across connections with 2 hose clamps to hold connections tight, if it doesn't start right away I go push on connections and it fires right up, Think I recall that there are 57 connections between the 2 connectors.

If the relay checks good there must be power coming out of the relay down the harness to the pump. A live fault then must be between the pump connector and the relay. following the harnesses and checking them out is one route. Maybe the ground from the fuel tank to the chassis is not attached. Did u check the power to the pump or are you just listening to see if it runs?
I would check that ground 1st.

1999 ford expedition 4.6L cranks but will not start

you might try starting fluid in air horn to see if it tries to run, then at least you would know it is not an ignition problem and only on the fuel side. Maybe wiring connector to crank sensor is bad. Really not sure how you would check if Anti-theft is preventing starting, but keys are only 1/2 of system and PCM is the other.

Crank but no start

What make , model an year vehicle ? Could be a relay problem , power hold relay for ford , ignition 1 relay for GM vehicles or ASD - auto shut down relay for jeep , dodge , Chrysler vehicles . Asian vehicles have them too , Honda - main relay powers fuel injectors , coils etc.... Do you know how to do basic automotive electrical testing ? Check for voltage ? You would need to look at a wiring diagram for your vehicle , see which wire powers the coil an injectors etc...test for B+ voltage ! Videos on you tube showing how to test ignition , fuel etc..

I have a 2005 jeep liberty crank no start, no codes. battery,plugs, coils, fuel relay/fuses,crank&cam position senors all good. injectors have good resitance and power. no fuel pressure. pump in...

Might check for power to pump. You have fuse (some have 2), relay, and pump. These pumps are common failure items, and the aftermarket offers several really poor quality replacements. Either get a Delphi brand, or dealer pump. If you drop the tank remember an empty tank is full of fumes which are more explosive than the fuel is. Don't use a trouble lamp with incandesent bulb; use battery flashlight. BE CAREFUL!

My 1993 E-350 club wagon wont start Code: 542 =

Replace the TCM to fix the converter clutch problem.. The line 12 volt is direct power from the battery and 7 volts out the I am suspicious off as I think that the coil for the relay is partially shorting out to give the 7 volts. As for the other wire 12 volts in would be ok but if there is nothing out unless it is a relay that has not closed because the relay coil has not activated correctly.. Check the readings against a new relay.

1989 cutlas cera wont start its giving me code 12

Code 12 is a "good" code-it means system normal.
Since no codes are stored, check for spark and check for gas-is the fuel pump coming on? You should hear the pump buzz for a couple of seconds when you turn the key to on-it should start and pressurize the lines, then shut off until the engine is cranked-when cranking, pump should be running again. If you don't hear the pump, check if the fuel pump wire at the gas tank connector has power to it when the engine is cranking. If it does and the pump is not working, the pump will need replacing.
If no power, check the fuel pump fuse and relay, under the hood.
If the fuel pump is working, it may be ignition related-check for spark. You need to see a blue snapping spark to know the ignition system is good. If no spark, suspect the ignition control module or the crank position sensor -or the pickup coil, if no crank sensor. The pickup coil will be in the distributor-if you have one. If no distributor, crank position sensor is behind the crankshaft harmonic balancer.
If fuel pump and spark are good, you will need to diagnose the injector circuit.
Post back with what you find.

Truck will not start... checked the wires... replaced battery... am getting fuel... all fuses are good...checked the wiring harness going to coil packs-have juice...checked the coil packs... took them

Normally we start with the basics, are the spark plugs firing and are the fuel injectors opening and providing fuel, and does the engine have compression.
Also, are there any stored trouble codes in the computer?
There is a relay that powers the injectors and fuel pump. You say you are getting fuel so we will assume that relay is ok.
The crank or cam sensor could have failed, or a list of other things.
You will need to figure out if you are lacking fuel or spark to the plugs to proceed.

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?

First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.
