ok......3rd gen prelude. fresh b20a5. wont run. she turns and turns and turns, but wont fire up. has fuel, has compression has spark, and timing is correct. all electrical seem correct, and nothing out of place. any suggestions?

we even tried spraying a little bit of ether into the intake manni to get her to fire up....but still a no-go. instead, she backfired through the intake and shot a pretty flame out the manifold

 

Do you have the wires plugged up to the right firing order on the dizzy?

 

yup

 

does it have an immobilizer cuz my 01 teg did this to me had to get it re keyd. it whould crank all day but not fire. just my 2 cents.

 

its an 89 B20A5 fuel injected

 

there is a relay that controls PGM-FI, should be around the interior fuse box. thats usually the problem when you have everything like spark ect. and it still dont start. GL.

 

thanks man, ill have a look at that......i was reading up on it last night, and from what i understood, it was a real pain to try and get a new relay...i guess because it is a certain type....i hope im wrong, anyone want to correct me on this?

 

they change by year, just pull it out when you go to the parts store to compare. I have a friend that bought one at advance, i think for 90, they are expensive. I recomend asking a friend that has the same type or relay (as long as the plug is the same it will work) and go from there.

 

are the injectors pulsing?

 

not that i know of. cylinders are getting plenty of fuel and you can smell it on the plugs so yeah....i dont think there is a problem on that aspect. i just think its wierd that when we sprayed starting fluid down the intake manni she backfired through the manni and shot out a fireball.....kinda scary.
