Hey there guys I have a problem. I have a 2nd gen 88 rx7 gxl. Cranks but wont start. Has newly rebuilt motor from atkins rotary. New maf and new coil packs. Push started once and it ran for about 15 minutes but it ran like crap.Have spark and timing is on have fuel. Any ideas would be most appreciated. Thanks alot

 

Verify the TPS is set correctly. Verify the MAF sensor is hooked up. Verify the various temp, coolant, & O2 sensors are hooked up. Verify sparkplugs are installed in the correct order.

 

+1 and spark plug wires-are you getting fuel/oil pressure?

 

And remember to break the engine in correctly!

 

Set up code lights. Theres a how to in the archives I believe. This will tell you if you forgot to hook something up(sensors and what not) or if theres a problem with a sensor or your maf.

 

Thanks for the advice so far. I triple checked the tps, maf, and every single other sensor i have on the vehicle. All my plugs are in the right order. And i do have fuel and oil pressure. But still nothing......

 

you might want to try push starting it again, sometimes fresh rebuilds need to be run for a few dozen miles before they make enough compression to start on their own

 

reading through..new engines tend to start hard..crappy for a little bit and alot of adjusting..push start a couple times to break in..it will start eventually on its own..imo..that's what i've read here..
