Another thing to check is that the timing belt has NOT jumped.
First remove fuel pump fuse and run engine until it dies then turn engine over couple more times to make sure it will not run while setting number 1 clyinder to TOP DEAD CENTER on compression stroke.
Remove #1 spark plug and turn over engine until you feel compression coming out of the spark plug hole. Then use a socket and racket connected to the crankshaft pulley bolt and turn match the timing marks on the harmonic balancer and engine block to TDC.
Mark the location of #1 distributor cap terminal on the distibutor base, remove distributor cap and see if rotor lines up with #1 cap terminal, if so timing belt is ok.
#1 spark plug in case you are not sure of location is on the bank closest to the firewall, plug nearest passenger fender.
