Hi all, I have a 1993 honda accord ex, it wont start. I have checked fuel pressure (45-50 psi) is what the gage read. Changed the fuel filter, fuel pump relay, and I have spark. What else can I check? Any and all help is most welcome. Thanks JD
Aside from fuel and spark the only other things needed are compression and timing. Can you see the rocker arms moving as you crank the engine over? If not, may be a timing belt issue. If they do move (the engine may still not be ‘in time’) but I’d check compression.
The belt is fairly new maybe 10000 on it and it is in one piece, dont know if the timing is out cant start it to see. Dont know about compression have not checked it but will thanks.

This is Eric’s video on compression testing. If you have fuel and spark, this is the next place to check.
I recently had this problem. A few things I found were that if the battery is getting low, it can cause a Low Crank Speed. Which wont allow the car to turn over. What turned out to be MY problem, the car had flooded, Just hold the gas pedal to the floor crank it till it stops cranking (the noise/jerking stops) and keep the pedal to the floor but stop starting the car and let the key fall back to run. When you hear it reving up let off pedal and let run for a while. It took a few times but it has since stopped doing that. Now when I turn my car on I just insert key and crank. Hope that helps 🙂

More ETCG goodness for you to view!
I would recommend posting this in the service and repair area for more replies and views.
This is the “Maintenance” section C8-)
Honestly I doubt it’s fuel related especially since you have great fuel pressure. BTW in the future if you have fuel pressure the main relay is not the issue as that causes the fuel pump not to run normally if it fails. This leaves us with spark and engine timing. You don’t need the engine to run to check the mechanical timing of the engine but you would need to remove the valve cover to check the marks on the cam while you also check the mark on the crank to see if they are in time. Before you do that however check to see if you have spark and if you don’t this video should point you in the right direction.

Lastly I recommend using OE ignition parts and if the wires are already OE leave them alone as they pretty much last forever but if they’re aftermarket I’d replace them with OE or NGK wires.
Cool thanks for all the information. I finally got an OBD code its 9 quick flashes, says its a #1 piston positioning senor. Where is this sensor? And does this mean it could be the timing? Thanks again.

Check timing or you might have a sensor issue in the distributor as well(I’m betting on this). you can save some money if the coil and ignitor are still good. Might be able to find a used one on craigs but might have to put some money into it to replace the dizzy.
I’m wondering if you have an aftermarket distributor, if you do replace it with an OE unit and see if the car starts then.
Replaced it today, with OE replacement distributor, still no start. And back to no codes on the OBD. Going back to the drawing board tomorrow, start with spark then fuel. Any other ideas???? Thanks again for the info.
Is your timing right?
Do you have good compression?
That will also tell you if your timing (mechanical) is way out.
