Hey guys, I just got a new engine for my 93 Accord and got it installed yesterday. It gets spark and starts when using starter fluid, but it wont run after a few seconds or without starter fluid. My mechanic thinks it could be a problem with some sensors, does anybody here know what I should look for? Any help is appreciated, thanks for your time.

1993 Honda Accord EX; Installed New engine, gets spark but wont start. Sensors?

It's not getting fuel, obviously. Are you using the old injectors, or new injectors? Do you hear the fuel pump prime when you turn the key?
My first thoughts are the injector resistor box (they go bad... rarely, but it happens) or the main relay (which would keep the fuel pump from turning on.)
Both of those would be an easy fix... and even cheap if you have a junkyard with a few CBs in it. That would be the first thing I'd check.
I'm assuming you installed another F22A6? (F22A1 if you're in Canada...)

The fuel pump does prime (I can hear the whirring when I start the car), Ive had to replace the Main Relay before, so I'll mention that. The fuel injectors are new.
Edit: Also, the car has been jacked up for almost 3/4 weeks. Is it possible the sensor thinks its upside down and not letting fuel go threw?

When you first turn the key to the on position check to see if the check engine light comes on for a few seconds then goes off. If it goes off and you hear the pump buzzing the main relay is probably ok. Check to make sure there is gas in the tank has gas in it and then check to make sure that all the fuel lines are tight. A loose clamp or fitting can cause that. Next try renting a set of noid lights at the parts store. You find one that fits the injector plug. Unplug an injector, put the noid light in the plug and have someone crank the engine over. The light should flash. If it does then its physically not getting fuel. If it doesn't flash then it's something electronic that's wrong.

So..new main relay, new injectors, good pump and it'll run on starting fluid
Have you checked your fuel pressure regulator? Maybe it's stuck open and the injectors aren't getting enough fuel.
