Question about 1988 Mercury Grand Marquis
Lets start at the beginning.
Did anybody check to see if the timing chain was really in need of replacing ?
Did you replace the starter and solenoid because it would not crank ?
Is it now getting spark to the plugs, and fuel to the injectors ?
Are the injectors getting voltage and a ground signal from the computer ?
Do the cylinders have proper compression ?
Is the rotor in the distributor turning when you crank the engine ?

SOURCE: NO SPARK OUT OF COIL.
usually those coils are pulsed at the ground wire end of the coil. So you could have 12 volts in. The question is...do you have 12v out the ground end?
If so then the coil pulseing unit may be bad.That signal,should come from the distributor....or maybe from the ECU Processor.
