I have a 91 accord that's driving me crazy and broke! I have replaced the distributor, cap, button, plugs, wires, main relay, fuel pump and filter, and the computer to get this thing to start. It's getting spark but the fuel pump isn't coming on when I try to start it? All the parts are new Wich has been costly! It just won't start? But if you spray starting fluid in the intake it will start until it burns off the fluid? Frankly I am completely at my end with this thing! I really need help figuring this thing out!

I have a 91 Chevy 1500 350 shortbed l replaced spark plug and wires ,distributor cap and rotor button, ignition coil ,and modular under the distributor..and a new battery..the truck is just turning over and won't start..ls it possibly l might have crossed one of my plug wires, l got the print out at a O'Reilly where I brought the parts from..

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

You forgot to replace the whole car or engine!

Could very well be the main relay, limiting power to all the electronics in your car, causing the problems you've mentioned. Have it repaired or replaced.

I believe its the main relay u are looking for. This relay controls the fuel pump and spark. Its located under the steering column. Grey in color and usually has one bolt attaching it. Hope this helps.

injector is faulty

no spark means bad coil, also check for cracked distributor cap. No fuel could mean fuel pump not gettin power or it is gone. or clogged fuel filter.l

cars wont start without fuel so it could always be A) fuel pump B) fuel filter C) fuel injecters dirty. any one of these will cause fuel not to reach your spark plugs and cause then eng not to start

Check to see if you have spark to your spark plugs. On hondas if you have no spark it wont let the fuel pump get power. This is controlled by a small part in the distributor called the ignitor by honda and ignition module in aftermarket terms. when this part goes bad you wont have spark or fuel. it is a pretty expensive part. sometimes its cheaper to get a used distributor at the junk yard and change the whole thing. also make sure your timing belt hasnt snapped cause if it did your distributor wont turn and you will get the same results. take the distributor cap off and check and see if the rotor spins while someone is cranking the engine. if it doesnt turn your timing belt is broke or your camshaft broke in half. broken camshafts are a common problem with 95 accords. If none of this helps you may have a wiring problem or even your cars computer may have taken a dump
