My rex is having difficulty starting up. it started up the 2 days ago for like 2-3 seconds then died. tried again a few moments after and it just cranks no turn over. i tried again today, it started then died after 2-3 seconds and then just cranks after that. i changed oil, filter, spark plugs and wires, put new gas, adjusted the dizzynothing. timings dead on. does anyone have anything on this? I Also posted a picture of my purge/ vaccum lines up if that has anything to do with it. Theyre possibly in the wrong spots. help a fellow Rex brother out lol

 

Test ignition switch.

 

Need more info:

What distributor and ecu did you use?
Did you convert to OBD1?
Are you getting spark?
Getting fuel?
Did you mess with any of the timing components, new timing belt?
When you turn to accessory does the fuel pump/check engine light cut on for two seconds then cut off?

 

its a p72 obd1 coverted to obd0. im using a chipped p28. i converted to obd1 with a jumper harness. i must be getting spark since the car does start up but then dies. yes im getting fuel, i took off the fuel return line and fuel comes out and also removed the banjo bolt from the fuel line that connects to the fuel filter and the filter leaks so i know its not clogged. timing belt is still good so i never changed it. i adjusted dizzy but that doesnt work so i moved back in place. i wouldnt know the check engine light doesnt work even after i put a bulb in. from my guess the the ecu isnt reading the MAP sensor because the vacuum/purge lines might be in the wrong spots. so the ecu doesnt know to inject fuel.

 

okay thanks.

 

pics of lines, ones not connect ends of in an elbow. wheres it go?

 

lines coming off canister.

 

where did you get the ecu jumper from? what about the dizzy wiring, did you use a jumper as well?

i had bought an ebay one, was too lazy to make my own, put it in car started up. couple seconds later i get a check engine light. i check the code and its for CKP, i check the wiring and turns out the idiots who made it tied the ckp+ signal to the o2 sensor wiring. never trust an ebay jumper. you get what you pay for.

with that said, double check the ecu jumper wiring.

 

i bought the ecu jumper from rywire. and i dont have an o2 sensor yet, low on cash. but is that may be the problem? what about those map sensor lines and charcoal canister coming from the charcoal canister? my ecu is tuned btw.

 

the elbow line goes no where i know its supposed to go somewhere obv but just dont know which spot. second i have a map sensor on my TB too but have the TB with the delete on it just havent put it in cuz im trying to get my car started so i can bring it to my school and finish all the little stuff there.

 

Just plug the MAP connector you have going to the firewall to the one on top of your throttle body or use this diagram. The purge solenoid stuff beside it can be deleted if you want otherwise use this diagram

 

Can you take more pics of your engine bay as well so I can see how you have the rest of the wiring and connections?

 

thank you much appreciated

 

ill be on it asap heading outside now to take somem pics should be up within the hour

 

so my problem is.that im not getting fuel. tested this by putting gas into the throttle body itll pudder but no start. fuel pump is working because filter will leakof bolt is cracked and my lines are getting fuel. is the injector clips supposed to be in a specific order?

 

they should only be able to reach their specific injectors:
Timing Belt Inj (brown) Inj (red) Inj (blue) Inj (yellow) Distributor

 

i had a buddy mess with the harness so he extended the wiring for the injectors but im going to check if thats the order right now.

 

yes

 

so my fuel pump is playing games and turning on and turning off. ill get fuel through the lines then i won't. i took removed the line from the fuel rail cranked it for a few nothing held it a little longer then fuel. fuel pump is definately acting up cant even hear it turn on. so im gonna test the main relay and harness see if something shows up then go to my fuel pump clip check that then last replace fuel pump. oh and im check #14 fuse under the dash (alternator) but i have a service manual from 1987 and it shows that that fuse controls almost everything to do with the engine.

 

1988 OEM HONDA CR-X SERVICE MANUAL FTMFW! this book literally tells and shows me how to do everything on a Crx (stock things anyway lol, even body and electrical work. i insist on getting one asap if you havent already. Well worth the money. Especially when people give the run around and aren't sure aout certain things. the book knows all lol
