Hey everyone, just getting on here for my first post, I recently bought a Maverick that had a blown engine, instead of getting it rebuilt I found another engine, it is however out of a Renegade, slight difference’s but nothing to bad. I have everything back together. It will roll over but not start, have double checked every connection, made sure my ground is good, brand new plugs, took injectors out and they spray nice and good every time, an In line spark tester and both cylinders are firing, I’m genuinely at a loss here, would the timing be different? Too much fuel because of the 10-1 vs 15-1 compression ratios between the mav and renegade? Any help would be amazing.
