1988honda accordLXI/turns over but won't start

Have you done a new fuel pump.

Pump or injectors may be bad .

The first thing I would check is fuel pressure. This type of fuel injection requires a minimum fuel pressure in order to operate. If fuel pressure is as little as one psi below minimum the vehicle will not start. You can try squirting a couple of shots of carb spray into the air snorkel while somebody cranks the engine over. If the engine starts and then dies you now you fpdeffinetely have a fuel issue. If the engine still won't start check for spark. Let me know what you find. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Fuel pressure at idle is normally 30-35psi. Start by taking the gas cap off, and putting it back on. That will De-pressurize the fuel system. Also, make sure you have gas in the car. I have seen gauges on these cars read wrong. I hope this helps.

you probably have air in the lines, if you have a carb, spray some quick start into the carb and turn it over, if it starts and then dies when the starting fluid has run out, you probably need a fuel pump, since the running of the car should have blown out any air that was in the line, If your car is fuel injected, loosen the bolt cap at the end of the injector line that supplies the fuel,, and tap the key once,, ( don't start it,, ) just turn the key on and off 3 or 4 times, this should blow fuel out of that loose bolt head, if it does your getting fuel, if not, back to the fuel pump, also you can check this link, http://www.aa1car.com/library/us1296.htm

Get some starting fluid and shoot it in the throttle bore while someone turns the starter ,if this starts the car this confirms it is a fuel problem if it starts. second check fuel pressure with fuel pressure gauge depending if it is carburetor or fuel injected (fuel injected is anywhere from 35 to 55 p.s.i) (carburetor type 8 to 12 p.s.i.) t.this is the starting point.check fuses to relays and if ok the fuel pump is at fault and needs to be replaced.
Thank you for your questions

TRY NEW FUEL FILTER /PLUGS AIR FILTER

No, you don't have to press the accelerator in fuel injected engines. That's a general rule for all fuel injected engines.

Carbureted engines require that you push the accelerator slightly when starting.

Good luck on using your fuel injected vehicle.

When were the glow plugs last changed?

They sit over the cylinder like spark plugs and warm the diesel before it goes into the inlet manifold, greatly assists starting.

Check the actual fuel pressure and make sure it is to spec. Fuel injected vehicles need a certain pressure to run.
