Hi I have a1988 chevy k1500 died changed coil dist wire from coil to dist have fuel no spark any ideas thanks

Fuel pump is a seperate system,unless it is a security fault.
Should be able to hear the pump run for like 3 seconds as you
switch the key on.
If it's a security fault the light on the dash should be lit ,or flashing.
No spark,check the rotor again,is it loose ,side to side?
The dist. may have a worn upper bushing,making the loss of spark.

pick up coil in the dist/ a bad module/a plugged cat

First you need to retrace your steps...before you changed the timing chain and gears did It run ok ? what was initial problem, next put a fuel pressure gauge on your fuel line and cycle your key on to run pos, dont have to try start, just run and see if you have fuel press during the 3 sec or so pump cycles, should be around i think 35-45 roughly for tbi. so if you have good fuel pressure , then you say you have good spark, then your problem is either ingition or valve timing, did your dist.come loose, did you properly install chain & gears and align timing marks. did you have somethine else a part on it too like intake, dist, ? get back with me I'll try to help you.

bad ingnition coil

Check coil for spark. Which type if Dist does it have? Should have High Enegry which are know for modueal in the dist going out.

Clean all main ground and power feeds for the battery and starter.

sounds like it could be the modular under dist. cap. i would replace the rotor button and dist.cap.

check the ignition modual under the dist. cap

computer coil power try to disconet the spout wire..... its under the hood by passenger firewall ....... its a brown wire or behind the glovebox

replace the ignition modulator inside the distributer. costs about $20 @ local auto zone! just had the same problem.
