I agree with the above comments. You have to be sure you got the firing order correct. If in doubt, look it up and double check it. When a car is backfiring, it can be from running the fuel too lean. You can always buy a compression tester tool and make sure you have compression on all cylinders.

Is the coil connected to the ditributor? did you knock any connections off in the process? Does it turn over but not fire? do you have spark at the plugs? Are you sure of cylinder location in respect to firing order? Did you-and check this first as with any elec. problems-blow a fuse in the ignition circuit? good luck!

With that kind of symptoms you should be displaying a check engine light have the codes extracted and get back to me let me know what codes and I will give you a better idea of what is wrong with your vehicle.

Is there any codes in the computer that will help with the diagnoses?The mapp sensor or mass air flow,witch ever it has could be the problem.Check the fuel pressure also.

I have a 1990 chevy pickup 1500, 2wd. auto. the problem os that it idels ok. while in park you can give it halg throttle it runs fine, but as soon as i put it in drive and drive it down the road it starts...
Check dist. cap and rotor and replace. Just fixed one last week. Rotor was causing a misfire under load and coil contact to rotor was worn out down too the cap. Graphite dust from the center contact in cap was all over the rotor causing a misfire. $25.00 in parts or less. While you are there replace wires and plugs. Autolite ap25 plugs 2.99 each

You have spark on the coil wire but not coming from the cap. You replaced the cap right. Did you replace the rotor too. Sometimes the rotor burn in the center and the spark goes right thru it in to the distributor shaft.

1990 K5 Blazer DIED(Electrical?)?
There may be no injector pulse if the computor does not see a RPM signal.
There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal.
Because you do not have both ......I would suggest to check/change the dist pick up.
Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist.
If it is just a bad dist pickup....keep all your old parts as good spares.
Also...is the dist turning? to provide a RPM signal?
You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal.
A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT POSITION......as you spin the dist by hand .....the injectors should spray.

Same thing happened to ours - probably the timing belt. New coil, cap, rotor, wires, hall sensor, and computer - still no spark. Had timing belt changed and presto - car starts.
